Pain during/after sex

So I was on top of my man and all was good but then he went on top of me and was in a position where he was able to get in REALLY deep. Immediately I felt a sort of burning type pain in my abdomen. What could have caused this? Him hitting my cervix? Once I got on top again I didn’t feel it with every stroke anymore but I still had the left over feeling. I’m still feeling it right now. Do you guys think it’s serious? No bleeding or any other symptoms and it’s never happened before. Also idk if this may be relevant but we had eaten right before this lol
