Ovulation calendar

See when you may be ovulating to help find your most fertile days.

Know when it's the best time to get pregnant

If you have a regular menstrual cycle*, use our ovulation calendar to help you figure out when you ovulate so you know when to have sex to try to get pregnant. Once you have results, sign in or sign up to save your calendar, add notes and find out when to take a pregnancy test. The calendar cannot and should not be used to prevent pregnancy. Use birth control until you’re ready to get pregnant.
