I had sex with my boyfriend two days ago but my vagina hurt after we were done. Yesterday we had sex again but blood came out. My period is due to end but the blood was different than the period one. It was lighter. Is it possible that he hurt me in someway? We ve been together for 6 months and we had unprotected sex a couple of times but that was months ago so I am freaked out cause I don t think is an STI since we didn t have any symptoms for months.
