Bleeding after sex

Catie
Okay so me and my boyfriend have sex atleast twice a week well I just got off my period two days ago and we had sex today after all the old blood was gone. Anyways we were in missionary position which we usually do doggy and he thrust deep and literally the worst pain in my abdomen and I just brushed it off and again the worst pain in my abdomen so he changed the angle but an hour later I'm bleeding? Like I have to wear a tampon bleeding, what the hell.😩
