Interactive Tool: When Are You Most Fertile?

What do the results tell me?

The results give you an estimate of the day you ovulate, which is when you have the best chance of becoming pregnant. It also shows the days before ovulation when sperm in the woman's reproductive tract can still result in pregnancy. Because a human egg typically lives for only 12 to 24 hours after ovulation, you are unlikely to become pregnant by having sexual intercourse the day after you ovulate.

If you are planning a pregnancy, do not have sex during the 5 days before your 6-day fertile window. (Not ejaculating for a few days helps build up a man's sperm count.) Then have sex once each day of your fertile window, including ovulation day.
