Можно ли забеременеть в первый день месячных?

It’s a common misconception that you can’t get pregnant on the first day of your period, but it is possible. Here’s how:

The first day of your period is actually the day you start ovulating. This is because the egg only survives for 12–24 hours after it’s released from the ovary. So, if you have sex on the first day of your period and you ovulate within that 24 hour window, it’s possible for the sperm to fertilize the egg.

Of course, there are other factors that come into play when trying to conceive, such as the quality of the sperm and whether or not you are using any form of birth control. But if you’re trying to get pregnant and you have sex on the first day of your period, there is a chance that you could conceive.
