I have wondered this since I had dd.
I heard that my whole belly would contract.
Mine DID NOT. My contractions were concentrated to just above my pubic bone. I didn’t feel them in my belly or back. It was 4 square inches of the purest pain I’ve ever felt. I’m shivering just remembering!
I had an epidural at 4cm and just wondered if I’d given in? Or if other’s contractions were easier? Totally unscientific straw poll!
