Has any mommies felt themselves start to dilate a bit? I know the difference between BH and real contractions..I've definitely felt real before. However, I know baby isn't ready yet but I sometimes feel "bearing down-gotta stop what I'm doing" pain. It's very quick and goes away but I'm just wondering if my cervix is starting to dilate or if it's even possible to feel that first 1 cm happen.
