Hi ladies, I'm 13 weeks today and today and yesterday I've had tightening feelings in my uterus, it's like cramping but it's less like period pains and more like braxton hicks-type feeling, it's just got me really worried...I googled hoping for reassurance, but pretty much everything for 13 weeks talked about round ligament pain and this isn't that, it's a fairly constant pressure/tight feeling. Does anyone have any thoughts? I also had some moderate lower back pain earlier but that didn't last long.
