Having sex during your period is a personal choice between you and your partner. There’s no medical reason not to have sex during this time, but remember: although it’s unlikely that you would become pregnant, it’s still possible. You should ALWAYS practice safe sex and use condoms 100% of the time, especially if you have sex during your period. Some sexually transmitted infections (STIs) such as HIV are known to spread more easily when blood is present.
