Natural fertility awareness methods

Discover fertility awareness with the fertility tracker Daysy!

Are you interested in fertility awareness methods and want to know how to determine your fertile days with a fertility calculator and an ovulation calendar? If you've already started getting into the topic of fertility awareness, you know that every woman is only fertile during a few days of her cycle and can only get pregnant during those days. This scientific fact enables you to only use contraception on your fertile days and refrain from using contraception during all infertile days. In order for this fertility awareness method to work and a pregnancy to be safely avoided, it is important to determine the fertile days as accurately as possible. Daysy can help you with that.

The fertility tracker Daysy: fertility awareness made easy

Daysy calculates your fertile days and your ovulation based on the natural range in your basal temperature. In the course of the female cycle, the basic body temperature changes slightly. It increases by half a degree starting the day of ovulation. The body maintains this higher basal temperature until the period sets in. This is referred to as a temperature high. Then again, from the start of the period until the next ovulation, the body maintains a temperature low. You don't notice these slight temperature changes, but Daysy's highly sensitive test prod  recognizes and evaluates them using its unique algorithm.

Daysy can therefore tell you straight after measuring your temperature whether or not you will be fertile during the next 24 hours. With this knowledge you can now either prevent a pregnancy by not having sex during those days or by using, for example, a condom. Or you use this knowledge to induce a pregnancy and have sex during your fertile days. With Daysy, you can determine for yourself how you handle your fertility, day by day. And all that without side effects, hormones or interferences with your body and your cycle!
