Is it like a cramp or just a constant pain? Maybe baby is pressing on a nerve. I've recently started having charlie horse type cramps in my inner thigh and I think it might be the baby's head or shoulders pressing on a certain nerve. It is very painful and surprising when it happens.
I am right there with you. It got really bad around 7months. I had never had that with the first. It subsided for a little while but has returned with a vengeance last week (36 weeks). I feel like I've been riding a horse for days on end!!!!!
