Should I be worried?

Baby girl always likes my right side anyway. I have been getting Braxton hicks and sometimes it it hard to tell if it is baby vs contraction. Right now I'm not sure but I just had sex a while ago and now my stomach is getting super hard mostly on the right side and when I rub there it will gradually relax and go down and she will kick. It has happened a few times within this past hour and it doesn't hurt but I'm 26 wks and just want to make sure she is okay. I know they say to monitor Braxton hicks but I'm really unsure if it her or contractions.
