Ovulation Calculator

Our ovulation calculator will let you know when you’re most likely to be fertile over the next six months.  In order to increase your chances of getting pregnant, just tell us the first day of your last period and how long your cycle usually lasts (between 20 and 45 days).

NOTE: This tool provides approximate dates only and assumes a regular menstrual cycle. If your menstrual cycles are irregular, you may have trouble pinpointing your day of ovulation based on this calendar alone.
