This online safe days calculator will help you calculate a safe period for sex or infertile and fertile days between your menstrual cycle. The goal is to prevent unplanned pregnancies and also to know on which days it is easier to get pregnant.
Calculation of fertile and infertile days
A woman’s menstrual cycle usually lasts about 28-30 days, in some cases 25-35 days (it can be a few days shorter or longer). But just a few days in a cycle is guaranteed to be fertile.
