I had intense pain in one area of my ribs (right side) about the size of a deck of cards.
It didn't move or leave when baby shifted, but it hurt like hell when she'd kick there, or when I moved funny.
Docs were somewhat concerned it was preeclampsia related (liver pain), but after thorough testing, it was determined I had an abdominal muscle that had torn away from my ribcage a bit. It will only get worse as I grow (it has), though it will get much better when I have the baby.
Hope you are feeling better, if it's pain on the right hand side, you might consider phoning your MW or doc.
