Weird popping in rib

So last night or early this morning I was in bed laying on my right side. I was sort of awake but mostly dozing off back to sleep. I stretched my body and felt this pulling then like a pop in my ribs on my right side. It hurt and woke me all the way up. Right after it happened the baby starting moving around a lot. Like a lot. I felt her pushing out and rolling on my lower left side. The pain in my rib is still there. Not as bad as that first initial pain but I can feel where it happened from the pain sensation.

Baby still seems to be active. This happened about two hours ago.

Has this happened to anyone before? Is it possible that she had a foot or something stuck in my rib and it popped out when I stretched ?

I’ll be 33 weeks tmrw.
