My oldest broke one of mine. It was very painful it hurt to breath also.
It's very possible, or it can be just dislocated, from the baby or even when your not pregnant you can easily dislocate a rib or two just by sitting up. The dr can tell you if it's just dislocated without an xray, and they can massage it back in place.
My son kicked me in the ribs all the time and because of it my ribs hurt all the time luckily he didn't break any...could be a possible bone bruise though. It seemed my son always kicked in the same exact spots.
It is possible. Do they hurt all the time? I thought she cracked my rib but turns out she is just cuddled up in there all the time.
When my friend was pregnant her son kicked her so hard it broke one of her ribs
