Are you looking for a menstrual calculator that lets you know when you are ovulating ? Do you want to know reliably when your next period and your next ovulation will be? Then Daysy is just what you are looking for! Daysy is a highly modern menstrual cycle calculator that calculates your cycle. Daysy does not only show you when your next period will be, but also calculates your fertile and infertile days reliably and fast.
You can always rely on Daysy without having to draw temperature curves or analysing your cervical mucus . The only thing Daysy requires prior to getting up and entering whether your have your period. Nothing else.
Simply calculate your monthly cycle with Daysy
In order for Daysy to be able to show you every day whether you are currently fertile, simply use it to take your morning basal temperature by activating it and placing its sensitive test prod underneath your tongue. Stay in bed while you wait for about 60 seconds for the measurement to finish. Daysy might then ask you to confirm that you currently have your period. That too is done via the simple and quick push of a button. Already Daysy has all she needs to calculate your fertility.
Right away, the result is displayed via a colourful light. If Daysy's green light is on, it means that you are not fertile for the current day. On your green days it is highly unlikely to get pregnant. If, however, the red light is on, you are currently fertile – and if the red light is flashing, you are highly fertile and currently ovulating . During red days you can get pregnant at any time.
Daysy's menstrual cycle calculator: accuracy through science
Daysy's accuracy has a solid scientific basis: More than three decades of research and development were necessary to make Daysy the safe device that it is. For the development of its unique algorithm, 5 million female cycles were recorded and evaluated. Beyond that, the LadyComp has successfully been using Daysy's software for many years and proven its value.
Did you know that every woman can only get pregnant during a maximum of six days of her cycle? Only on the day of ovulation, as well as up to five days prior, is conception even possible, because the egg can only be fertilized for up to 18 hours after ovulation . If no fertilization takes place during this time, no pregnancy will ensue. The reason for your additional fertile days is that sperm can wait for the egg inside the fallopian tubes for several days. Once the fertile period has passed, you will not be fertile until your next fertile phase.
Daysy lets you know when your fertile and infertile phases are happening. To get pregnant, you can use your knowledge to increase your chances for a pregnancy by having sex at the right time. Regardless of your situation, you can use the menstrual cycle calculator Daysy in a way that fits your individual life and plans.
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
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.
You can confirm or remove menstruation at any time during the current day. Simply press the button to turn on your Daysy, and then press and hold the activation button until the violet light lights up without flashing and you hear a "beep." Confirm you are menstruating for each day of active bleeding and for a minimum of three consecutive days. You can also remove menstruation data for the same day by turning Daysy on and pressing and holding the activation button until the purple/blue light is no longer solidly lit and begins flashing again.
The first 2-4 cycles of use are considered Daysy's learning phase. Over the course of her learning phase, Daysy will come to understand your cycle and begin narrowing down your fertile window. Daysy remains quite cautious and conservative during this time, which is why Daysy is accurate starting the very first day.
You can rely on Daysy's results starting the very first day of use. In the beginning, you will see more yellow and red days because Daysy is still learning your unique cycle. You will see more green days as Daysy comes to understand your cycle and can narrow down your fertile window. The more regularly you measure, the better.
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.
