Rib/Side Pain?

Tr

I'm 37 weeks and you know that cramp/pain/soreness in your side you get if you run too far too fast without stretching first? My entire right side feels that way, starting at the top of my ribs, going down my side and wrapping around to the middle of my back.

It's been this way for several hours now and nothing seems to help it. I know it's not my baby, because she's hanging out on my left side and her feet are currently in my left ribs.

Anyone else experience this? Any ideas for relief? Is this normal or should I call my midwife? I just don't want to call if it's nothing serious, but this HURTS
