Sex question?

Im currently 18 weeks and 4 days pregnant and my question is have any moms have pain on the side of there pelvic during or after sex?

I feel it on my right side and its not extremely painful but if i bend down or touch it i feel it. It just started yesterday we only had sex once yesterday and onetime this morning but i made him stop today bc i feel the pain.

And its not rough sex lol we both know im pregnant already
