After about a week postpartum (when I started moving around more), I started to get this weird crampy, ow, feeling in my abdomen when I go to the bathroom. I remember this a little right after the births with my first two but its been almost 3 weeks now and I still am feeling it. Maybe even stronger now. Is this normal? Is it just my insides moving back in place and healing? My mom said maybe its just nerves coming back. Anybody know?
