This is the rule of thumb (I learned this at the Bethesda Naval Hospital where the President gets treated.): A female ovulates 10 days after the first day of her last period. Ovulation lasts about a day and a half. Remember though, this can vary from woman to woman. The sure fire way to prevent pregnancy is to use condoms and the pill or a diaphragm or something like that.
