How do they work?

Daysy and Lady-Comp are fertility monitors that use the fertility awareness method (FAM), that is they learn and track your menstrual cycle. You can then use this information to plan or prevent pregnancy just as you choose. Daysy and Lady-Comp will show you if you are fertile or not with an accuracy of 99.3%. It is all natural, free of side effects and no charting is necessary.

Just 60 seconds once a day….

  • Every morning, take your temperature under your tongue
  • Confirm menstruation days
  • Lady-Comp and Daysy evaluate your data and calculate your fertility status for the next 24 hours

Both devices operate with a three-colour light fertility indicator:

red-light (Red light) – When you get a red light, you are fertile. If pregnancy is not wanting to be achieved, you will need to use a barrier method of contraception such as condoms, a diaphragm, or a sponge.

yellow-light (Yellow light) – Yellow days indicate cycle fluctuations and learning phase. To avoid pregnancy, you should treat these the same as red days, and use a barrier method.

green-light(Green light) – Green indicates not fertile and you can enjoy moments with your partner care free.
