## What is Fertility Calculator?

Fertility Calculator or Ovulation Calculator.

Menstrual periods are different from woman to woman and month to month. Use this calculator to see when you may be ovulating to help find your most fertile days.

The fertile period is the ideal time to get pregnant. Also characterized by ovulation and its signs, it normally occurs on average 14 days before menstruation and lasts around 6 to 7 days. With the aim of helping those trying to identify this moment, the FERTILITY CALCULATOR or OVULATION CALCULATOR was created.

Just say the first day of your last period and how long your cycle usually lasts (anything between 20 and 45 days). The calculator will tell you which days you should be most fertile.

The Fertility Calculator serves to make life easier for those who are trying to get pregnant and as not everyone knows how to calculate fertile period easily, the fertility calculator will help.
