unprotected sex on your periods

Jennifer
Hey girls! Soooo me and my man had sex and he came in me. We got caught up in the moment and it just happened. Usually we are sooooo careful and don't do anything stupid cause I'm not on any birth control (due to medical issues) 
Anyways he came twice and I'm super scared if I could be pregnant. We had sex on the 3 day on my period! Any comments or anything will help HAHAHAH low key freaking out!
