FAQ

In order to help you to get off to a good start with Lady-Comp and Teena, we have listed the answers to the most frequently asked questions here

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.
How long does it take to measure?

It will take approximately 60 seconds to measure.
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.
Can I transfer my data to other Valley products at a later time?

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.
Does the "Teena App" work with Android and iOS?

Yes, "Teena App" works with most Androids and iOS. The app can be downloaded from the Apple App Store or Google Play Store. The app store description will give you information on the latest app version and software requirements.
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 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.
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.
