Rough sex?

Had rough sex with my husband. Almost 13 weeks. He was on top of me against my stomach and as I was trying to get to my orgasm, my stomach was starting to hurt. Like an ache. Could it be something wrong with baby? No spotting and the ache was only that time when he was pressed up against me so rubbing stomachs together lol. I don’t really have a belly so I’m not sticking out but just was concerned if I should be worried or not?
