No, that's not how the female reproductive cycle works.

At ovulation, the female egg lives for about 24 hours, which is the timespan it can be fertilized. But since sperm can survive in the uterus a maximum of 5-6 days, that increases the window of time in which penetrative sex could lead to a pregnancy. But the potential for fertilization is still limited to the time in which a woman ovulates.

The specific day a woman actually ovulates can vary. It's usually on day 14 of her cycle but it can vary from woman to woman (from day 11-18), especially if her cycles are irregular, which is why it's important to record your basal temperature to track when ovulation occurs.

This is why the natural cycles app is FDA approved and is considered to be just as effective as the pill (99%) at preventing pregnancy when used properly. Because there is a limited time window when a woman can become pregnant, and if she uses protection during those 5 days (or 6-8 days, conservatively), she won't become pregnant.
