Anyone else have this happen?? I was laying down feeling my son move around when I get a pain like cramp or thought it was braxton hicks. Its lasted a little over 10 mins and hasnt gone away. It hurts a little less when Im standing... About to take a shower and hope it helps. Any ideas on what it could be? Yes I will call my OB or go in if it doesnt go away. But really don't want to spend my 4th at the drs if I dont need to.
