First time pregnancy- so unsure if this is normal or not? Was walking the dog today and had to bend down to hold her as another dog was going by when I suddenly felt this strong muscle tightening pain in my groin/vaginal area, took my breath away slightly but as I slowly stood up it loosened off and disappeared. It happened a few more times on the walk when I was bending over but has gone completely now. Heard a comment about it possibly being the baby moving into position but I don't know? Can anyone help me out?
