Ovulation Calculator
Ovulation Calculator
Find out when you're likely to ovulate -- and increase your chances of getting pregnant!
Just tell us the day you last started menstruating and how long your cycle usually lasts (anywhere from 20 to 45 days), and we'll tell you when you're most likely to be fertile over the next six months, as well as your approximate due date if you do conceive on one of those 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 the calendar alone. In that case, you should try monitoring your basal body temperature and cervical mucus. To learn how to do that, read our article on detecting ovulation.
