Sever cramping

Brigitt
I have been waking up with pretty bad cramps that go away within an hour but this morning I woke up with the worst of it, I can hardly move or bend without extreme shocks of pain in my pelvis and abdomen. Should I be worried and go to the ER or is this pretty common and will subside with time? I'm a first time mom and just really worried and in a lot of pain.
