Frequently Asked Questions Daysy, Lady-Comp and Teena

Teena: How do I use Teena?
How does Teena work?

Teena is programmed with a complex algorithm which evaluates your cycle by tracking your morning temperature (taken under the tongue) and knowing when you have your period. The Teena App will then display your measured temperature value and the current phase of your cycle.

I forgot to enter my period. What do I do?

You can edit your menstruation input up to 3 days retroactively. Open your Teena App and select the date you want to edit. Select the plus (+) sign and then touch one of the drops corresponding to your flow amount. Swipe down to close this screen and you will see the period confirmed in the daily details.

I had a sleepless night. Can I still use Teena?

You can always rely on Teena. If you have to skip a measurement after a sleepless night, Teena will still display your cycle phase. Depending on where you are in your cycle, Teena will react accordingly.

How long until Teena knows my personal cycle?

The first 2-4 cycles of use are considered the learning phase. Over the course of the learning phase, Teena will come to understand your cycle and begin predicting your next menstruation with accuracy.

How often should I take my temperature?

It is best to try and measure your temperature every day. The more days you use Teena to measure your temperature, the better Teena can learn and predict your cycles.

How do I activate Teena before the first measurement?

Before you can begin using Teena, you must first synchronize with the Teena App to activate your device and create an account. Place your thumb on the touch field (for 4 seconds) until you see a slowly flashing turquoise light, to turn Teena on. Teena is now ready to connect to the app. Open the Teena App and follow the onscreen instructions to pair your Teena. If you have already been using Teena App in Free Mode, open the Account menu and select Register, then follow the on-screen instructions.

How long does it take to measure?

It will take approximately 30 seconds to measure.

How do I switch Teena off?

Teena automatically switches off after 60 seconds.

Where do I measure with Teena?

Below the tongue in the pocket next to your lingual frenulum (that’s the muscle line you feel running along the underside of your tongue) and with your mouth closed. It is best to measure on the same side each morning with the sensor tip lightly touching the bottom of your tongue if comfortable.

When can I start using Teena?

You can start using your Teena right away.

Should I keep measuring my basal body temperature after a vaccination?

First things first: If you feel that there is something not right, you feel sick, or you have pain, never hesitate to consult your doctor! Most people tolerate vaccinations without any problems. Sometimes, however, vaccination reactions occur: These are almost always harmless after-effects of vaccinations, which in the vast majority of cases pass very quickly. Some vaccinated people react with a slight fever (below 39°C / 102°F), aching limbs or faintness. The fever can occur only a few hours after vaccination and last up to 3 days. Such vaccination reactions are usually completely harmless and no cause for concern. As a rule of thumb: If you wake up in the morning after the vaccination and feel different than usual, for example sick or overtired, then interrupt the measurements until you feel better again.

I am traveling to a different time zone. What do I need to do?

When staying in other time zones, synchronize your Teena with the Teena app after your arrival and your phone’s time has updated. If the time difference is more than 6 hours, we recommend skipping the measurement on the same day and the following day. You can resume your measurements as usual on the day after.

Will Teena be correct while I am taking medication?

That depends on whether the medication influences your body temperature or your cycle. In general, you should skip measurements while you are taking such medication. If you have doubts, contact your doctor or our support team.

Does illness reduce the reliability of my Teena tracker?

In general, you should skip measurements when you are sick and while you are taking medication that can have an influence on your body temperature or cycle. If you have doubts, contact your doctor or our support team.

What do I do when I stop using Teena?

Store your Teena in a cool, dry location. Teena will be ready to resume use whenever you are. If you are ready for a more in depth look at your cycle and fertility, your data can be transferred to the Daysy fertility tracker. Contact your local support team for more information.

Which medication can influence my measurements?

Only very few (hormone-free) medications have a direct influence on your measurements, but often the reason why you are taking medication can influence your temperature (e.g. fever or stress). Hormonal medication will influence your temperature. If you're unsure, consult with your doctor or contact our customer service.

What happens if I miss a measurement?

Because Teena has an intelligent algorithm, it can compensate for the occasional missed reading. We still recommend you measure as regularly as possible so that Teena can predict your next menstruation as precisely as possible. If you have to skip measurements due to illness, Teena will get back on track once you start again.

How can I clean and disinfect Teena?

Use a damp cloth to carefully clean the sensor of your device. You can also use a little alcohol or soap if you wish. Since Teena is not waterproof, make sure that only the sensor and not the whole appliance comes into contact with water. We recommend the following steps for cleaning: 1. Clean the sensor and tip with lukewarm water and/or mild soap before and after each use. 2. Dry with a clean cloth. These steps will reduce the number of germs or possible viruses on the surface of the device. This cleaning is sufficient for daily personal use. If the device needs to be disinfected as well, the following steps can be practiced: 1. Wash your hands thoroughly or wear disposable gloves. 2. Clean the sensor and tip (as per steps 1 & 2 listed above). 3. Moisten the sensor and tip with a disinfectant (limited virucidal), alcohol (60-80%) or isopropanol 70%. 4. Allow to air-dry (the sensor should not touch any other objects or surfaces).

Information COVID-19: We are taking precautions as necessary, with staff wearing gloves, use of Personal Protective Equipment and increased cleaning methods. All products are disinfected prior to shipping. Coronaviruses are encased viruses, meaning they are encased in a lipid envelope. All disinfectants with a virucidal (antiviral) or limited virucidal spectrum of efficacy are effective against coronaviruses. A list of all tested and approved disinfectants to fight Covid-19 is available from United States Environmental Protection Agency found here: www.epa.gov The agents listed can inactivate the corona virus, which means it loses its ability to be infectious. This can be done in different ways: · Denaturation -> destruction of the virus surface · Removal of lipids from the virus envelope -> e.g. alcohol · Impairment to the nucleic acid of the viral genome Alcohol is capable of destroying the virus shell and can often be found already in your home. Alcohol that is 60% alcohol is effective in inactivating the virus. However, 100% alcohol is not effective because only alcohol with a proportion of water allows the lipids to be dissolved from the virus envelope. An alcohol volume between 60% and 80% is therefore recommended. Isopropanol (70% )is also a suitable agent for the inactivation of COVID-19. You can learn more about cleaning and disinfection for households from the Centers for Disease Control and Prevention here: www.cdc.gov

How can I edit menstruation input retroactively?

You can edit your menstruation input up to 3 days retroactively. Open your Teena App and select the date you want to edit. Select the plus (+) sign and then touch one of the drops corresponding to your flow amount. Swipe down on the card and you will see the period confirmed in the daily details.

How can I check my measurement status later in the day?

Touch and hold the touch field on your Teena and your measurement status will be indicated by the color of the flashing light. Turquoise means a temperature was recorded; orange means the temperature was not recorded or was unsuccessful.

Can I measure multiple times per day?

No. Teena will only record the first measurement of the day.

I missed a couple of measurements. What should I do?

One or two skipped measurements are not a problem; Teena will simply use your earlier data to calculate your cycle. Multiple missing values per cycle may make it difficult for Teena to predict the start of your next cycle.

Do I have to measure at the same time every day?

No. What is important is that you measure immediately upon waking after getting at least 1 hour of sleep, before getting up and being active.

Should I also use Teena during my period?

Yes, please take your temperature throughout your entire menstrual cycle. However, on some days you should refrain from taking a measurement: for example, when you are ill (fever) or when you did not sleep at least 1 hour.

What do the Teena tracker display colors mean?
  • Flashing orange light
    = Teena is ready to record a measurement
  • Flashing turquoise light
    = Your temperature has been successfully recorded / Teena is ready to synchronize with the app
  • Flashing orange and turquoise light = The temperature measurement was not completed. Let Teena fall asleep and then restart the measurement.
What is the best way to measure?

Use Teena in the morning right after waking up, before getting up and out of bed. Measure below your tongue, with your mouth closed. We do recommend that you sleep at leats 1 hour before measuring.

Teena: General questions
Does the Teena tracker come with all the necessary accessories?

Yes, your initial Teena order includes everything you need.

Do hot weather or air conditioning have an influence on the measurement?

No, since you measure below the tongue, these factors have no influence on the measurement.

Teena doesn’t allow menstruation entries prior to 3 days in the past. However, you can begin recording and syncing your temperature as soon as you have activated your account on the Teena App. Teena will start tracking with your first temperature and you can explore the cycle journey and magazine articles.

Can I use Teena if my sleep schedule varies?

Yes! Everyone has problems sleeping from time to time, stays up late, or sleeps in. It does not matter for this method because it recognizes and evaluates its own pattern to display the follicular and luteal cycle phases.

How long can I use Teena? Only while I'm a teenager?

Teena is not just for teens. You can continue to use your Teena for as long as you want. When you are ready for a more in-depth view of your cycles, ie knowing fertility statuses, you can have your data transferred to another Valley Electronics product such as Daysy or Lady-Comp.

Teena: Questions about my period
When will I get my first period?

Your first period (also known as menarche) is individual to you. Your first period will likely not happen at the same time as your friends’ first periods. On average, first periods arrive for pre-teens when they’re around 12 years old. But your first period may come earlier or later.

How will I know when I’m going to get my first period?

There are a few changes you will experience before the arrival of your first period. Before you get your first period your breasts will begin to develop, you will notice pubic hair growing under your arms and around your vulva area, and you will have a growth spurt. When your first period’s arrival is getting closer you will probably see some white cervical fluid in your underwear.

How often will I get my period?

If you recently started getting your periods and you have irregular cycles, don’t worry: this is normal! A major study from the World Health Organization discovered that on average the first cycle you have after your first period is 34 days. That means there were 34 days from the first period day to the start of the next period. If you’ve been taught to expect all menstrual cycles to be 28 days in length, it might surprise you when your own cycles don’t match up. But, in reality, 38% of menstrual cycles studied by WHO went on as long as 40 days. For 10% there were more than 60 days between the first and second period. 7% had a first cycle length of 20 days.

Menstrual cycles are usually more irregular in the first year or two after you get your first period. As you get older, they usually become more regular. This is because anovulatory cycles (menstrual cycles without ovulation) happen more often when you begin getting cycles, especially if you got your first period before your teens.

How can I prepare for my first period?

A great way to start preparing for your first period is to learn all about the magic of your menstrual cycle and for this you’ve come to the right place! The more you learn about periods, the more confident you will feel when you start having cycles. Knowledge is power!

Secondly, you can prepare by putting together a first period kit for yourself, with your parent, or with your friends. This should contain period care products like pads, a change of underwear, and maybe some wipes. You can carry this with you to school in your bag or if you go on a sleepover. Usually periods arrive at school because that is where you spend a lot of time! If you’re worried about leaks, you can always have an extra shirt or sweater in your locker to tie around your waist if it happens. But know that everyone experiences leaks and it’s okay!

What is a period?

Your period may look like blood, but it’s actually different to the blood you will see if you cut your finger, for example. It contains blood, but also cells and tissue and nutrients from the inner lining of your uterus. About once a month your body signals to your uterus that it should let that lining go, and it lets it go out of your vagina onto a pad or into a tampon or cup. Menstruation follows ovulation - that’s when your body releases an egg - after a certain amount of days. Hormones make ovulation happen and then they make menstruation happen in a predictable process that is your menstrual cycle!

What period care products can I use?

Shopping for your period can be fun! There are four main period care products for you to choose from - pads, tampons, menstrual cups, and period panties. Pads come in different shapes, sizes and absorbencies so it’s a good idea to get a multipack at first so you can figure out your flow. Tampons also come in multipacks. With both pads and tampons, you will use several a day and throw them in the trash when they’re used. There are also menstrual cups and period panties. With menstrual cups you will empty and wash it, then use it again. With period panties, you might wear all day and then switch in the evening, putting the used panties in the laundry basket. All of these options are great for someone who has just started getting their period. You can try them all in the next few months and see which you like best. You might pick just one or decide to use two, like say a tampon and period panties or a cup and a pad.

How long does a period last?

How long your period lasts (which means how long will you actually see period blood) can be different for you than your best friend, but for most tweens and teens a period lasts, at most, 7 days. Some of those days (mainly at the start and the end) you will see very little period blood at all. Using Teena to track your period will help you to get to know how long your period normally lasts and be prepared for future periods.

Do periods hurt?

Cramps happen, but not everyone gets cramps.

If you do have the mild pain of cramps, this will usually come on when your period is just starting. You might feel them in your belly area or your lower back area. Cramps come in waves and may feel like a dull ache or sense of pressure.

While some cramping is common and many of us do have cramps for some periods, the pain should not be so bad that it stops you from going to school or having fun with your friends.

How much blood is there?

Much less than you expect! An average period is about four tablespoons of period blood at most. Go fill four tablespoons with water, juice, or soda and put it in a glass! See, it’s not much at all.

How can I clean period blood?

There might come a time when you want to get period blood out of some of your favorite underwear, pajamas, or bed sheets. First of all, a parent or trusted adult can help you, don’t feel like this is something only you have experienced, most people who get periods (or love someone who gets periods!) have had to clean up period blood! The best way is to use cold water from the tap instead of hot. Just run a little cold water on the spot and rub it, you’ll be amazed at how quickly it disappears.

What if I am not getting my period?

It is normal for cycles to fluctuate. If you're unsure, feel free to contact our customer service.

More: Contact
Is a 45 day cycle normal?

Yes, that is very normal for a teen. The importance is that a good portion of these cycles are ovulatory.

Will other people know when I have my period?

No, unless you tell them, no one will know you have your period.

If you’re worried about leaks consider taking an extra shirt or sweater to school and leaving it in your locker. That way you can always tie it around your waist if you need to. But even if there are stains, know that usually they are small and not noticeable to anyone else. Otherwise, you look just the same when you’re on your period as when you’re not.

That said, feel free to tell whoever you want about having a period and feel proud!

Teena: Questions about your body
What is this white stuff in my underwear?

White or off-white or transparent “stuff” in your underwear that may look streaky or be stretchy or even globby is likely cervical fluid. You will see cervical fluid before you get your first period and during your menstrual cycles.

Cervical fluid protects the uterus from bacteria from the outside. It also plays an important role in helping sperm get to the egg for conception. When we plan for a family, we can know when we’re able to get pregnant by looking at our cervical fluid.

If you notice other kinds of fluid from your vagina that is yellow or green or looks like cottage cheese, especially if you also feel itching or burning, that can be a sign of infection. If you’re concerned about this, talk to your doctor or a trusted adult.

My cycle is irregular. Can I still use Teena?

Yes. Irregular cycles are not a problem for Teena. As your cycles become more regular, Teena will be able to more accurately predict your next menstruation. If you have questions about your unique cycle, please reach out to our team of experts.

Teena: Questions from Parents
Are there any tips for getting my teen to agree to use this?

Let your teen know that Teena helps alleviate the anxiety over when the next period will arrive. The app makes learning about her cycles and changing body fun; and she can learn in privacy, at her own pace, without feeling awkward or embarrassed. As an added bonus, the app allows positive, supportive time on their phone.

How long until a teen cycle regulates?

It takes around 8-10 years for a menstural cycle to regulate for a teenager.

Have you had a test group? Do teens stay consistent with it?

Yes, we had a test group for 6 months. After a brief learning curve, they stayed consistent and actually enjoyed the self check in every morning

How is data stored? I am uncomfortable with the idea of my daughter's data being tracked.

The Teena App does not collect any personal data, such as name, email address or phone number. The account is created using the Teena device serial number. If no Teena device is being used, a virtual device ID is created. During the sign-up process a recovery key is also generated and is known only to the user of the app. An account can only be logged into with the combination of device serial number (or virtual device ID) and the recovery key. In order to display the cycle phases and menstruation predictions, the temperature and menstruation data is transferred to our server for evaluation. Since we know how sensitive this data is, it is transferred in an encrypted (https) and anonymized format to our servers within the European Union, and stored there. This means that even if unauthorized third parties were to gain access to the servers, it is not possible for the data (basal body temperature, menstruation, ovulation) to be associated to a specific person. This special protection is very important to us.

What will my daughter learn on the App?

Teena app provides valuable knowledge about everything related to the female body and being a teenager. A daily display of the body temperature (if using the Teena device) is accompanied by a simplified display of the basal body temperature curve and cycle phases, as well as positive affirmations. The Cycle Journey is an animated journey through the different phases of the cycle, from the hormones released in the brain, to the egg's path from follicle to uterus, all the way to the beginning of the next period. Short magazine articles are provided to discuss the hormones and what they control, female anatomy and self-care tips for the period. The content, written by experts and illustrated in a contemporary way, helps young women develop an awareness of their body and their femininity and use it as the superpower it is.

Daysy: How do I use Daysy?
What is the best way to measure?

For optimal use of Daysy, we recommend that you should have slept sufficiently (at least one hour) before the measurement. It is important that you take your temperature immediately after waking up, before getting up and becoming active. Measure below your tongue, with your mouth closed, and keep the device steady while it is measuring. Video Tutorial

I want to start using Daysy after a pregnancy. What do I do?

Please contact your customer service for guidance.

More: Contact
Can I measure multiple times per day?

No. Daysy will only record the first measurement of the day.

How can I check my fertility status later in the day?

Simply press the activation button and your fertility status will be displayed.

I missed a couple of measurements. What should I do?

One or two skipped measurements are not a problem; Daysy will simply use your earlier data to calculate your fertility. Multiple missing values per cycle will lead to a higher number of red or yellow days.

When can I start using Daysy?

You can immediately start with the measurements. If you were using hormonal birth control before, stop using it before you begin measuring. The first bleeding after coming off hormonal birth control is a withdrawal bleeding and must not be entered as your period. If you are menstruating when starting with Daysy and you cannot enter all days, do not enter the current menstruation, but the next one. The first day of menstruation is important because it marks the beginning of your cycle.

Where do I measure?

Below the tongue in the pocket next to your frenulum and with your mouth closed. It is best to measure on the same side each morning if comfortable.

I am slowly approaching menopause. Can I still use Daysy?

Yes, you can. Daysy is also reliable during the transition to menopause. If your ovulation is delayed or doesn't occur, Daysy will display more red and yellow days. Using Daysy will allow you to directly observe the changes that are happening to your cycle.

Can I use Daysy during breastfeeding?

Yes, Daysy can be used while breastfeeding. You should not start measuring until 6 weeks after birth. Since there is no way to predict the first ovulation after birth, Daysy will stay yellow until the first menstruation is entered postpartum. Once you enter your first period, Daysy will display fewer red and yellow days in the following 2-4 cycles as Daysy gets to know your unique cycle rhythm.

Is there something I have to be aware of when traveling to a different time zone?

Daysy 1.0: If you traveled overnight, skip the first measurement after your arrival and continue to measure regularly the next day after resuming a normal sleep cycle. Do the same thing when you return home from traveling.

Daysy 2.0: When traveling with your Daysy, it is important to set the time on your Daysy to the local time before resuming your temperature readings. Set your mobile phone to the local time zone (many phones will do this automatically) and synchronize your Daysy with DaysyView/DaysyDay to set the time on Daysy. Take your temperature and resume use as normal the next morning.

I had a sleepless night. Can I still rely on Daysy?

Yes, you can always rely on Daysy. Be sure to use Daysy daily right after you wake up, before you get up and get active. For optimal use of Daysy, we recommend that you have at least 1 hour of continuous sleep before measurement. If you have to skip a measurement after a sleepless night, Daysy will still reliably display your fertility status. Depending on where you are in your cycle, Daysy will react accordingly.

How long does it take to measure?

It will take approximately 60 seconds to measure.

Is it possible to delete individual measurements?

No. Daysy only records the first daily measurement. If you have concerns about a reading, please contact our customer service team.

More: Contact
Do I have to measure at the same time every day?

No. You should have at least one hour of good quality sleep before the measurement. It is important that you take your temperature immediately after waking up, before getting up and becoming active. For optimal use of Daysy, try to get at least 3 or more hours of sleep before measuring. Less sleep can result in more temperature fluctuations causing Daysy to give more fertile or potentially fertile days.

How do I know when I am fertile?

When Daysy displays a red light, it means that you are fertile. You can check your status anytime by activating Daysy.

My sleeping intervals are irregular (rotating work shifts, getting up at night, sleeping in on the weekend, etc).: Is Daysy also suited for me?

Yes. Daysy has been designed for women like you. Be sure to use Daysy daily right after you wake up, before you get up and get active. For optimal use of Daysy, we recommend that you have at least 1 hour of continuous sleep before measurement.

Daysy 1.0: Daysy only registers one measurement after 18 hours have passed since your last reading.

Daysy 2.0: Daysy only registers one measurement per day. If the next day has not yet started, a tone (beep-beep) will sound.

I have to get up frequently during the night because I have a baby. Can I use Daysy even with little sleep?

Yes, but be sure to use Daysy daily right after you wake up, before you get up and get active. For optimal use of Daysy, we recommend that you have at least 1 hour of continuous sleep before measurement. Daysy can handle skipped measurements from time to time.

Should I also use Daysy during my period?

Yes, please take your temperature throughout your entire menstrual cycle. However, on some days you should refrain from taking a measurement: for example, after excessive alcohol consumption, when you are ill (fever) or when you are feeling very bad.

How do I enter or edit menstruation?

Questions about my cycle
My cycle fluctuates. What happens if my cycle is longer/shorter than normal length?

Our devices expect a certain amount of normal irregularity. Cycle lengths of 19-40 days are the ideal requirement. The statistics display the ovulation range. If your ovulation fluctuates by more than 4 days or if your cycle length lies outside the 19 - 40 day range, please contact our team of experts.

What if I am not getting my period?

It is normal for cycles to fluctuate. If you're unsure, feel free to contact our customer service.

More: Contact
Does my diet affect my cycle?

Certain "strict" diets can lead to cycle irregularities, often times causing your period to come later. If you're unsure, reach out to our support team.

My cycle is irregular. Can I still use the devices?

Yes. Irregular cycles are not a problem for Daysy/Lady-Comp. Even with irregular cycles, all Valley devices distinguish between non-fertile and fertile days with a very high accuracy. However, in case of extreme fluctuations between cycles it will give you more red and yellow lights and less green lights. Fluctuations of several days are usually not a problem. If you have questions about your unique cycle, please reach out to our team of experts.

Which medication can influence my measurements?

Only very few (hormone-free) medications have a direct influence on your measurements, but often the reason why you are taking medication can influence your temperature (e.g. fever or stress). Hormonal medication will influence your temperature and should under no circumstances be taken in combination with Daysy or Lady-Comp. If you're unsure, consult with your doctor or contact our customer service.

When should we see a doctor if we do not achieve pregnancy?

If your efforts to become pregnant have not been successful within six to twelve months, consult your physician.

Do common pain medications (such as Ibuprofen, Naproxen, Paracetamol, ACC) have an influence on my basal temperature?

No, over-the-counter pain medication will not influence the measurements. The common additional antifebrile effect does not influence the basal temperature. However, please do not temp if you're using these medications to control a fever. If you're unsure, please contact our customer service.

What are some of the typical things that can influence the measurements?

● excessive amounts of alcohol

● sleep deprivation

● disease or illness

● chronic physical or emotional stress

● significant exercise

● strict dietary restrictions / starvation

● malnutrition

● travel

Once you know the cause, many irregularities in your cycle are easy to reverse. Feel free to reach out to our customer service to discuss your temperature curve.

Lady-Comp: General questions Lady-Comp
What do Lady-Comp's display colors mean?

Red = fertile / possibly fertile (On red days you can plan for a pregnancy.)

Green = non-fertile days (You are not fertile on green days.)

Yellow = learning phase/cycle fluctuation (Yellow days should be considered as potentially fertile days.)

Bright blue = possible pregnancy

Dark blue = probable pregnancy

Will my displayed fertility status be correct while I am taking medication?

That depends on whether the medication influences your body temperature or your cycle. In general, you should skip measurements while you are taking such medication. If you have doubts, contact your doctor or our customer service team.

Does illness reduce the reliability of the device?

In general, you should skip measurements during illness and while you are taking medication that can have an influence on your body temperature or cycle. If you have doubts, contact your doctor or our customer service team.

What do I do when I stop using Lady-Comp/Pearly?

Remove the battery and store the device in a dry location.

How long until Lady-Comp/Pearly knows my personal cycle?

The first 2-4 cycles of use are considered as learning phase. Over the course of the learning phase, Lady-Comp/Pearly will come to understand your cycle and begin narrowing down your fertile window. The devices remain quite cautious and conservative during this time, which is why Lady-Comp/Pearly is accurate starting the very first day.

Should I keep measuring after a vaccination?

First things first: If you feel that there is something not right, you feel sick, or you have pain, never hesitate to consult your doctor! Most people tolerate vaccinations without any problems. Sometimes, however, vaccination reactions occur: These are almost always harmless after-effects of vaccinations, which in the vast majority of cases pass very quickly. Some vaccinated people react with a slight fever (below 39°C / 102°F), aching limbs or faintness. The fever can occur only a few hours after vaccination and last up to 3 days. Such vaccination reactions are usually completely harmless and no cause for concern. As a rule of thumb: If you wake up in the morning after the vaccination and feel different than usual, for example sick or overtired, then interrupt the measurements until you feel better again.

How often should I take my temperature?

Ideally, you measure daily. The fewer measurements you miss, the better.

Can I share Lady-Comp/Pearly with a friend?

No, Lady-Comp/Pearly is your individual fertility tracker with your individual data.

How does Lady-Comp/Pearly work?

Lady-Comp/Pearly is programmed with a complex algorithm which evaluates your cycle by tracking your morning temperature (taken under the tongue) and knowing when you have your period. Lady-Comp/Pearly will then show you right away the measured temperature value and if you are currently fertile or not.

Does Lady-Comp/Pearly come with all the necessary accessories?

Yes, your initial Lady-Comp/Pearly order includes everything you need.

I am currently taking the pill. How can I change to Lady-Comp/Pearly in this case?

Before you start using a cycle computer, you must stop taking the pill. It influences your body’s hormone production. As soon as you have stopped taking the pill, you may start measuring your temperature with your cycle computer. Please be aware that the first bleeding after coming off hormonal birth control is a withdrawal bleeding and must not be entered as your period. If you are menstruating when starting with your fertility tracker and you cannot enter all days, do not enter the current menstruation, but the next one. The first day of menstruation is important because it marks the beginning of your cycle.

Which medication can influence my measurements?

Only very few (hormone-free) medications have a direct influence on your measurements, but often the reason why you are taking medication can influence your temperature (e.g. fever or stress). Hormonal medication will influence your temperature and should under no circumstances be taken in combination with Daysy. If you're unsure, consult with your doctor or contact our customer service.

What happens if I miss a measurement?

Based on their recorded data, our fertility tracker can compensate for the occasional missed reading. We still recommend you measure as regularly as possible so that your fertile phase can be narrowed down as precisely as possible. If you have to skip measurements due to illness, Lady-Comp/Pearly will get back on track once you start again.

Do alcohol or smoking influence the measurement?

Smoking should not influence the result. Alcohol, if consumed excessively or when your body is not used to it, does influence basal body temperature. If you can feel that you were drinking yesterday, you should skip your reading in the morning. If you feel just fine and have no headache or other symptoms of alcohol consumption, you are fine to temp as usual.

Can I continue to use the non-hormonal IUD?

The non-hormonal IUD prevents the implantation of a fertilized egg in the mucous membrane of the uterus. Because the IUD is a foreign object inside the body, it causes the production of white blood cells - similar to inflammation. These small centres of inflammation in the uterus, which are normally not detected at all, can change the waking temperature. In order to obtain precise measurement results, it is therefore advisable to remove the spiral - and only then use a cycle computer.

My cycle fluctuates. What happens if my cycle is longer/shorter than normal length?

Lady-Comp/Pearly expects a certain amount of normal irregularity. For optimal use of Lady-Comp/Pearly, cycle lengths of 19-40 days are the ideal requirement.

I am travelling to a different time zone. What do I have to bear in mind?

When staying in other time zones, set your cycle computer to the local time immediately after arrival and activate the alarm. If the time lag is more than 6 hours, we recommend skipping the measurement on the same day and the following day. Instead, you continue to measure as usual on the day after.

When can I start to rely on Lady-Comp's results?

You can rely on Lady-Comp's results starting the very first day of use. In the beginning, you will see more yellow and red days because they Lady-Comp is still learning your unique cycle rhythms. You will see more green days as the device comes to understand your cycle and can narrow down your fertile window. The more regularly you measure, the better.

When can I start using Lady-Comp?

You can immediately start with the measurements. If you were using hormonal birth control before, stop using it before you begin measuring. The first bleeding after coming off hormonal birth control is a withdrawal bleeding and must not be entered as your period. If you are menstruating when starting with Lady-Comp and you cannot enter all days, do not enter the current menstruation, but the next one. The first day of menstruation is important because it marks the beginning of your cycle.

I have to get up frequently during the night because I have a baby. Can I use Lady-Comp even with little sleep?

Yes, but be sure to use Lady-Comp (or Pearly) daily right after you wake up, before you get up and get active. For optimal use of Lady-Comp, we recommend that you have at least 1 hour of continuous sleep before measurement. If you don't get that during certain nights, there is no reason for concern. Lady-Comp (or Pearly) can handle skipped measurements from time to time.

Lady-Comp/Pearly: How do I use Lady-Comp/Pearly
Do I have to measure at the same time every day?

No. But be sure to use Lady-Comp daily right after you wake up, before you get up and get active. For optimal use of Lady-Comp, we recommend that you have at least 1 hour of continuous sleep before measurement.

Can I use Lady-Comp/Pearly during breastfeeding?

Yes, our fertility trackers can be used while breastfeeding. You should not start measuring until 6 weeks after birth. Since there is no way to predict the first ovulation after birth, Lady-Comp/Pearly will show yellow (learning phase/cycle fluctuation) until the first menstruation is entered postpartum. Once you enter your first period, Lady-Comp/Pearly will display fewer red and yellow days in the following 2-4 cycles as Lady-Comp/Pearly gets to know your unique cycle rhythm.

Is it possible to delete individual measurements?

No. Lady-Comp/Pearly only records the first daily measurement. If you have concerns about a reading, please contact our customer service team.

More: Contact
Do hot weather or air conditioning have an influence on the measurement?

No, since you measure below the tongue, these factors have no influence on the measurement.

My temperature rises just ever so slightly. What does it mean?

If for some reason, the increase in temperature is very low, Daysy will switch to displaying red days for a longer period, before switching to yellow days and, eventually, back to green days. A low rise in temperature can be an indication of a hormonal condition. During anovulatory cycles, no rise in temperature is registered because ovulation did not occur. Corpus luteum insufficiency (CLI) is another possible reason for a low or indeterminable rise in temperature because the body doesn't produce sufficient progesterone to make the basal body temperature (BBT) rise. Menopausal women can also register lower increases in temperature, because their estradiol and progesterone values are declining.

Is it possible that my temperature rises too sharply?

Not really. On average, a woman's temperature increases by 0.3 degrees Celsius. If yours rises by more than 0.5 degrees Celsius on average, please contact our customer service.

My Daysy won't let me take a temperature reading. Why is it making a "beep-beep" or "grumble-buzz"sound?

Daysy 2.0: The "beep-beep" sound is Daysy's way of indicating that temperature reading has already been recorded for this day. Please wait and take your temperature tomorrow morning. A temperature reading can only be recorded once a day.

The red indicator lights up and the activation ring flashes at short intervals. What do I do?

Daysy 2.0: Please contact your local customer support team.

How can I clean and disinfect Daysy?

Use a damp cloth to carefully clean the sensor on your Daysy. You can also use a little alcohol or soap if you wish. Since your Daysy is not waterproof, make sure that only the neck on the sensor and not the whole appliance comes into contact with water.

We recommend the following steps for cleaning your Daysy:

• Regularly clean the sensor tip with water and/or some mild soap after use.

• Dry with a clean, soft cloth.

• Replace the protective cap after drying.

These steps will reduce the number of germs or possible viruses on the surface of the device. This cleaning is sufficient for daily personal use with Daysy.

If the device needs to be disinfected as well, the following steps can be practiced:

• Wash your hands thoroughly or wear disposable gloves.

• Clean the sensor neck and tip (as per steps 1 & 2 listed above).

• Moisten the sensor neck and tip with a disinfectant (limited virucidal), alcohol (60-80%) or isopropanol 70%.

• When necessary, a cotton swab can be moistened with disinfectant and inserted into the protective cap to clean the inside.

• Allow to air-dry (the sensor neck should not touch any other objects or surfaces).

• Place the protective cap back on your Daysy.

I took out the battery. What happened to my data?

Daysy 1.0: The battery should not be removed for any reason. If Daysy's battery loses contact, it will stay yellow until the next menstruation is entered. The data you have already saved within Daysy is still there.

Daysy 2.0: Daysy does not have an accessible battery compartment. Please do not attempt to open your device or remove the battery as this will automatically void the warranty.

The activation ring no longer lights up. What do I do?

Please contact customer service.

What does it mean when a question mark appears on the start screen?

If Lady-Comp has not received a measurement or menstrual input for a longer period of time (> 4 days) and a new cycle start is expected during this period, this message reminds you to make up for any entries you may have forgotten. If you had your menstruation during this period, add it before the next measurement.

Can my measurements get lost?

No. Lady-Comp stores all your data and keeps it safe for years. We have users who have stored 25 years of data safely on their Lady-Comp device.

How can I clean and disinfect Lady-Comp/Pearly?

Use a damp cloth to carefully clean the sensor of your device. You can also use a little alcohol or soap if you wish. Since Lady-Comp/Pearly is not waterproof, make sure that only the sensor and not the whole appliance comes into contact with water.

We recommend the following steps for cleaning:

  1. Clean the sensor and tip with lukewarm water and/or mild soap before and after each use.
  2. Dry with a clean cloth.

These steps will reduce the number of germs or possible viruses on the surface of the device. This cleaning is sufficient for daily personal use.

If the device needs to be disinfected as well, the following steps can be practiced:

  1. Wash your hands thoroughly or wear disposable gloves.
  2. Clean the sensor and tip (as per steps 1 & 2 listed above).
  3. Moisten the sensor and tip with a disinfectant (limited virucidal), alcohol (60-80%) or isopropanol 70%.
  4. Allow to air-dry (the sensor should not touch any other objects or surfaces).

Information COVID-19:

We are taking precautions as necessary, with staff wearing gloves, use of Personal Protective Equipment and increased cleaning methods. All products are disinfected prior to shipping.

Coronaviruses are encased viruses, meaning they are encased in a lipid envelope. All disinfectants with a virucidal (antiviral) or limited virucidal spectrum of efficacy are effective against coronaviruses. A list of all tested and approved disinfectants to fight Covid-19 is available from United States Environmental Protection Agency found here: www.epa.gov

The agents listed can inactivate the corona virus, which means it loses its ability to be infectious. This can be done in different ways:

· Denaturation -> destruction of the virus surface · Removal of lipids from the virus envelope -> e.g. alcohol · Impairment to the nucleic acid of the viral genome

Alcohol is capable of destroying the virus shell and can often be found already in your home. Alcohol that is 60% alcohol is effective in inactivating the virus. However, 100% alcohol is not effective because only alcohol with a proportion of water allows the lipids to be dissolved from the virus envelope. An alcohol volume between 60% and 80% is therefore recommended. Isopropanol (70% )is also a suitable agent for the inactivation of COVID-19. You can learn more about cleaning and disinfection for households from the Centers for Disease Control and Prevention here: www.cdc.gov

Where can I order spare parts (cable, sensor, etc.)?

If no replacement parts are shown in your shop, please contact your local distributor.

Is it possible that my temperature rises too sharply?

Not really. On average, a woman's temperature increases by 0.3 degrees Celsius. If yours rises by more than 0.5 degrees Celsius on average, please contact our customer service.

My temperature rises just ever so slightly. What does it mean?

If for some reason, the increase in temperature is very low, Lady-Comp/Pearly will switch to displaying red days for a longer period, before switching to yellow days and, eventually, back to green days. A low rise in temperature can be an indication of a hormonal condition. During anovulatory cycles, no rise in temperature is registered because ovulation did not occur. Corpus luteum insufficiency (CLI) is another possible reason for a low or indeterminable rise in temperature because the body doesn't produce sufficient progesterone to make the basal body temperature (BBT) rise. Menopausal women can also register lower increases in temperature, because their estradiol and progesterone values are declining.

Do hot weather or air conditioning have an influence on the measurement?

No, since you measure below the tongue, these factors have no influence on the measurement.

Where can I check the battery charge level?

Lady-Comp: Go to the settings and open the menu "Device Information". Pearly: The device cannot display the battery charge level.

As soon as you see a battery icon on the start screen, you should change the battery/batteries soon.

Lady-Comp/Pearly didn't take my temperature. What do I have to do?

If the device did not take your temperature, try to repeat the measurement. Make sure to hold the device still and your mouth closed while you take your temperature.

Lady-Comp: If the measurement was not recorded after the second attempt, go to the settings, open the "Test Measurement/Demo Mode" menu and activate the test measurement. The measurement starts directly afterwards. If this attempt is also unsuccessful, please contact your local customer service.

Pearly: If the measurement was not recorded after the second attempt, please contact your local customer service.

What type of battery will I need for Lady-Comp/Pearly?

Lady-Comp runs with 2 AAA batteries and Pearly with 1 AAA battery. You can also use rechargeable AAA batteries.

How long is the battery life?

The battery life of the battery/batteries we supply with your order is at least 6 months.

Data Privacy
How secure is my personal data with Daysy, Lady-Comp, and Teena?

All three devices place great importance on data privacy. Your personal cycle data is stored locally on the device and is only transmitted in anonymized form if you use additional features such as cloud backups or apps. Daysy and Teena use modern encryption technologies to protect your information. Lady-Comp does not have an app; the data stays on the device.

Are my cycle data uploaded to the cloud?

  • Daysy: Cycle data is stored locally on the device by default. An optional app allows encrypted cloud backups.
  • Lady-Comp: Stores data on the device.
  • Teena: Usually uses app integration, where data is transmitted encrypted.

Who has access to my data?

Only you have direct access to your cycle information. When using an app or cloud services, the data is encrypted and can only be accessed with your device’s serial number. As manufacturers, we cannot directly access your personal information without this serial number.

Can I delete my data?

Yes. All three systems provide the ability to completely delete your data—both locally on the device and in the app or cloud. This permanently removes your cycle information.

How anonymous is the data for studies or analyses?

If manufacturers use data for scientific studies, it is anonymized. Individual users cannot be identified.

Are there differences between Daysy, Lady-Comp, and Teena regarding data privacy?

  • Daysy: Local data storage, optional encrypted app synchronization. . Lady-Comp: Local storage.
  • Teena: App-based; data is transmitted and stored encrypted.
