I have the most severe rib pain and I don't know why. Jr is kicking super low, why would my ribs (left side only) be hurting this much? Its been a constant pain since 9pm yesterday.
I had the same problem at 30 weeks, had a normal checkup and an ultrasound, it turned out that her head was right under my ribs and that's why they were hurting. so maybe it's your babies head :)
same side for me too!!!! I thought my rib was broken or something
