Can you get pregnant if you have sex while you are in your period?
Yes — it’s possible to get pregnant if you have unprotected sex during your period. However, it’s less common for this to happen.
Here’s the deal: A woman is most likely to get pregnant from sex that happens just before and during ovulation (when an egg is released). Ovulation happens in the middle of the time you get periods, usually about 14 days before your period starts. It’s more likely that you could become pregnant from sex during your period if you have a shorter menstrual cycle.
All of this might sound really complicated, especially if you aren’t sure how long your menstrual cycle is, or when you’re ovulating. During the first few years that you have a period, it’s pretty typical for your menstrual cycle to be irregular — which makes this stuff even harder to keep track of. But if you use a birth control method like condoms or the pill (both is even better) every time you have sex, your chances of getting pregnant are really really low, whether you’re on your period or not.
