Period and pregnancy?

A

Please someone help me,‼️‼️ I can’t find info for this question to get answered in the internet! 😫 Hear me out‼️

So if you’re on your period and for some reason become pregnant during your period does your period automatically stops?

Example if you have a 7 day period and have sex the 3rd day during your period will it stop the next day or will it get shortened? Or will you finish your cycle?

Someone help
