okay mommy's I need a little ftm advice. I have been cramping today.. it doesn't hurt it's just uncomfortable.. on scale of 1-10 it's about a 5... i only really cramp when I am laying down or up walking around if I am sitting in a chair I don't feel them as much... I also have also lot of pressure down below that is about an 8 on a scale of 1-10 and it really hurts when she moves and kicks or when I am up walking around... my back has been cramping along with all of this as well as my belly tightening.. is this early labor or false labor??? I will be 39 weeks tomorrow and at my 38 week check up I had not dilated but was thinned... any help??
