Pain in pelvic area

Okay so last night me and my SO had sex and it didn't hurt till towards the end when my left side pelvic area starts to hurt. And it would only hurt when he'd go in me and it hurts today as well now. Could it be that he just was doing it to rough and it made me sore their? And was just slitting that side to much or something else?
