Contractions??

So been having off and on Braxton Hicks contractions throughout pregnancy. I’m 32 weeks 3 days. Get home from work today and my stomach continually gets hard back to back and is uncomfortable so I drink water, swap positions. Can’t get relief. Well now it feels like I’m having diarrhea cramps. 😭😭😭 I don’t feel the need to go poop but idk what I should do! Help!
