Fertility calculator

Getting pregnant is mainly a question of timing. The female body is ready for conception only in the days around ovulation. With the help of our ovulation calculator, you can find out quickly when your ovulation is, and thus when you are at your most fertile.

Please note: the fertility calculator is not to be used for contraception!

First day of the last menstruation:

Tage (on average 28 days, if you do not exactly know how long your cycle is)



Key:
