Braxton Hicks?!?! Help

So I’m 30 weeks and I think I may have just had Braxton Hicks contractions

I felt I like I had to Poop but nothing was coming out it was like period cramps on my lower back but more painful and it would come for about 5-10 seconds and go away they stopped but now it feels like my baby is rolling in there any insight would help I’m obviously a first time mom and have no idea what that was
