Pinched nerve type pain in middle of back - 33 weeks...normal?

I’m 33 weeks and for a few days now I’ve been getting a pain the middle of my back on my right side in this one spot it feels almost like a pinched nerve whenever I am in a sitting position or standing for too long.

I literally can’t go in the car. I also feel a pain under my rib on the right side at the bottom of it when sitting at times that almost feels like a bruise?

Anyone else have this? What do you think it is? What can I do to ease the pain? This really sucks! It’s super uncomfortable.
