Horrible rib and back pain.

Hey ladies. I'm 22 weeks and experience horrible, take your breath away, rib pain. It wraps around to my back as well sometimes and I have to just sit up and push through it until it goes away. It only last for no more than 2 minutes, IF THAT, and doesn't happen too often.

It's happened before when I was like, 15-20 weeks. (Somewhere between there)

It wakes me from my sleep now and I'm just curious if anyone knows what it is? Or what's causing it?

I've talked to my dr when it first started and didn't get too much info so maybe I need to ask again, lol.
