27 weeks pregnant with rib pain

This is my first pregnancy and I have been waking up in the middle of my sleep, with this terrible pain under my ribs on the right side. It hurts to breath, roll over, or even move at all! It also only starts hurting when I’m laying on my right side.. I know it’s not baby because i don’t think he’s big enough to get stuck up there yet, and I can feel him move toward my lower stomach during the pain in my ribs.. has this happened to anyone else? I plan to talk to my dr about it but was wondering if this is a common thing or is something wrong?? TIA!
