Re: Someone told me...
Actually if you have long cycles, you will ovulate approx 14 days prior to menses. Not right in the middle. For example, I have about 45 day cycles. Ovulation usually occurs 14 days before the onset of menses. But yeah, if you have normal 28 day cycles it usually happens around day 14, which is in the middle. But like Whitewolf said, it can vary by a few days. And if you mean can you get pregnant only if you have sex on the day you ovulate, the answer is a strong no! Sperm can live a long time inside a woman. But it is the day that you actually conceive, for up to 24 hours, the life of the egg.
