Don't leave it all to chance if you're trying to get pregnant. Find out when you're most likely to be ovulating and increase your chances of conceiving. Tell us the day you last started menstruating and how long your cycle usually lasts, and we'll tell you when you're most likely to be fertile over the next few 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 works best for women with a regular menstrual cycle.
