so today my boyfriend and i had sex and today was the day after my period ended (he just couldn’t wait because my birth control brand got switched and messed up my cycle so we’ve been waiting like two weeks) anyways, he started hitting me from the back and i felt like a pain down there and in my lower abdomen and we stopped for a second. i told him to go again and it hurt still but a little less. i bled quite a bit this time and i’m still spotting 10 hours later with slight cramping. could this be because my cervix is bruised?
