Q: Can you get pregnant four days after you have your period?

A: Every woman has a different "fertile" time based on her cycle length and hormone regularity. The first day of your menses (your period) is Day #1 of your cycle. It is impossible to become pregnant on Day #4 of your cycle because there's not enough time to mature an egg in 4 days. However, if you are not having a "regular" cycle each month then your ovulation (fertile time) may not be "normal."  It is always best to practice safe contraception if you do not have cycles that are regular enough for "natural family planning" and if you do not want to become pregnant.

That’s false information. It’s not impossible or to early to get pregnant 4 days after your period finishes because I myself got pregnant 3 days after my period finished. And so many people say if you have a longer cycle you will ovulate later 15-20 days after your period. My cycle is 35 days and my period is 7 days and I got pregnant straight after my period finished. So yes you most definitely can and you know your body better than anyone.

Cycle day 4 and 4 days after your period ends are different. If you have a 7 day cycle for example, and you got pregnant 3 days after it ended, you would’ve become pregnant on day 10 of your cycle, not day 3. And since sperm can live maybe up to a week after intercourse, someone with this cycle could have possibly become pregnant up to day 17 of their cycle from intercourse 3 days after their period ended. Just hypotheticals, but the cycle starts the day your period starts.
