I'm 32+4 days pregnant. My stomach started tightening up and every time I have very uncomfortable pressure on my lower tummy. My back has started to hurt pretty bad (just figured that was normal) but I started feeling my stomach tighten and very uncomfortable pressure. Its not horrible pain. Just wondering if anybody has an idea what it could be. Maybe Braxton hicks contractions? Idk its my first time with all this. And baby has been moving just fine.
