Reliable and precise from day one thanks to the Daysy fertility calculator.
Calculating when you are in your fertile or infertile phase is no easy task. To be precise, you need reliable data. Daysy makes it simple to know when you are fertile by taking your waking temperature, tracking this data, and calculating when you are in your fertile and infertile phases. Daysy indicates your fertile window with reliability and precision. A pregnancy can be specifically planned with this knowledge.
These factors play a role in calculating your fertile days:
Menstrual cycle length: A cycle starts on the first day of menstruation (= 1st day of cycle) and ends on the day before the next menstruation. Each cycle is different and can even vary.
Your basal body temperature (waking temperature) is slightly lower in the first cycle phase and increases by 0.25-0.45°C around the time of ovulation.
Record all measurements and remember other factors that could have an influence, such as an infection or fever.
Understanding all of the above information and calculating your fertility status every day.
Sounds like a lot of work? Well, it is! That is why we developed the Daysy fertility monitor, so that you can calculate your infertile and fertile phases more easily.

The woman's cycle: medical basics
There are some basic physiological facts with regard to the cycle:
Every woman has only one ovulation per cycle.
If two or more instances of ovulation occur, they take place within 24 hours.
After ovulation, the ovum is fertile for a maximum of 18 hours.
Sperm is able to move and fertilize in a woman's body for a maximum of 5 days.
This means that pregnancy most likely occurs on 6 days, i.e. 5 days before ovulation and on the day of ovulation itself. Daysy calculates these 6 days and then indicates them to you.
Variations in the menstrual cycle: No cause for concern
Every woman has her own unique cycle, and it is not necessarily the same every month. Daysy fertility monitor learns your unique cycle rhythm and how to assess it. At the same time, it gives you a sharpened awareness of your body.
Your cycle is influenced by your emotional state too. Stress and other factors can affect your body, which can have an impact on your cycle. By recording your data on a daily basis, Daysy fertility monitor is able to recognize and indicate these changes in your life.
