Thanks for asking this!
Whether someone chooses to have sex on their period is totally up to them!
However, pregnancy is also still possible when someone has sex on their period because pregnancy depends on ovulation ( when the egg is released from the ovary) and ovulation can happen anytime during the month.
Also, STIs can be transmitted through genital to genital contact, sexual fluids AND blood, there would be a higher risk of STI transmission. Condoms can reduce the risk of STI transmission by 98% when used correctly.
In addition to using a condom, it would be a good idea to be on a form of birth control as well. Most forms of birth control can reduce the risk of pregnancy up to 99% when they are used correctly.
