I've been having moments where my stomach tightens up and I honestly thought they were just Braxton hicks, but lately they've been more painful or when they happen it feels like the top of my uterus is torn on something and I had some reddish brown mucusy discharge early this morning. I'm 38 weeks and a first time mom so I was wondering if it could be early labor and if it is if it's normal to feel less movements from the baby and just more pressure from her?
