Medical basics related to the female cycle
Every woman is different,
but there are some basic physiological facts about the woman's menstrual cycle that you should know:
As a rule, 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 can be fertilized within 18 hours at the most.
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 fertility tracker calculates these 6 days, plus provides buffer days.
How exactly does the Daysy fertility tracker work?
Daysy uses a proven algorithm and the morning measurement of your basal body temperature to calculate the daily menstrual cycle status in real time. Just measure your temperature under your tongue in the morning and enter your menstruation if you have it. Daysy will then display if you are in your fertile phase or not using red or green indicator lights.
The technology-based temperature method used by Daysy is one of the most reliable methods in the world for fertility tracking.
In addition, Daysy records your menstrual cycle and ovulation history and DaysyView displays your past and present cycle data. It is hardly easier to become aware of your body.
Daysy is a medical device and lifestyle fertility tracker. Daysy allows every woman who wants a health-conscious lifestyle to monitor her individual monthly cycle and determine her fertile and infertile days in natural harmony with her body.
