I woke up today feeling like I'm starting my period. My uterus/vagina is really achey & crampy and I have dull lower back pain. Generally it feels like my LO tried to beat me up from the inside & now I'm all bruised & battered. I've been having Braxton Hicks for a couple weeks now but they don't really hurt - it's just intense tightening that then goes away. What's weird is this crampiness is consistent, rather than coming & going like BH.

Is this just another wonderful part of being pregnant or should I be concerned?
