Once the woman’s body releases an egg (ovulation), it will live for 24-48 hours, and must be fertilized during this time for pregnancy to occur. However, sperm can live in a woman’s body for up to 5-7 days, so you can technically become pregnant if you have sex up to 1 week prior to ovulation. If you know the date of ovulation, anyone you slept with up to 1 week prior and for several days afterward could be the father of the baby. If you don’t know the date of ovulation, anyone you slept with since the first day of your last period could be the father. If there is any doubt about the paternity of the child, the only way to prove it is a DNA test.

BTW, Once conception occurs, it will take an additional 6-10 days for the fertilized egg to travel to the uterus and implant itself in the lining, thus establishing pregnancy.

That would depend on when you had sex relative to when you ovulate. Sperm can live in your body for 3-5 days — the egg dies within a day. So, there is roughly a 6 day range when sex can lead to conception and from there to pregnancy. (It only takes a few hours for the sperm to swim from the vagina into your tubes, so if there IS an egg waiting, conception could occur within a few hours.)
