Pain during intercourse?

Hello again everyone! 
​I have a question, have any of you ever experienced a weird pain during sex?
​I'm about 11/12 DPO now, and yesterday me and my fiancé had intervourse, and I couldn't help but notice a weird feeling throughout intervourse, it was like a strange dull ache on the right hand side of my uterus or where one of my ovaries are , and I have never felt it before! I was told by a friend she felt the same sort of thing when she was in her very early stage of pregnancy, do you know if this is true or common? It only hurt while we were having sex.
