Ahhh normal je tu at 33 weeks! A few of us went through the same thing, perut mengeras, rasa macam nak poop habis, but nothing comes out That's usually just Braxton Hicks (false contractions), especially if it goes away when you rest and baby is moving around normally. True contractions usually come in regular waves, makin kuat, and don't stop even when you change position, so kalau it only happens when you baring a bit then hilang, you're probably fine lah! But if the pain gets really intense or you start bleeding/leaking fluid, best la check dengan doctor just to be safe, first time mum, better be sure kan?
