33 weeks and cramping!!

I’m 33 weeks tomorrow and I’ve been experiencing super frequent (what I think are) Braxton Hicks contractions!! Like within an hour I get 4 or 5 of them and they last a few minutes each. My belly gets super hard and I feel intense pressure on my pelvis to the point it almost hurts to stand up during them. I also have been having on and off cramping like period-type cramps that come and go. I’m not seeing a specific pattern with them but they definitely are happening often. Has anyone else experienced/gone to their OB for anything like this!? I’m a first time mama and idk when to call or when I’m gonna found dumb for calling over nothing 😭
