Yes. A lady i know never even looked pregnant her tummy was reallyyyy small. Her dr said the baby was in her ribs & thats why she wasnt showing.

I feel that same thing, as if a limb is pushing up or something, I assumed it was organs running out of space or something

I didn't feel ds up in my ribs until 28 weeks. I have 1 friend who's son broke one of her ribs and another who's daughter dislocated one of hers lol.

Stephkc - this is also my second child. I don't remember feeling this with my daughter till I was about 30 weeks or so. I deff feel something going on up there but idk what it is

Baby was up just below my ribs at 20 weeks so it's possible. This is my second tho so I've already been stretched out.

Bruises, not brushes.

I don't know if they can be under your ribs, but Ds was born with brushes on his feet from sticking them in between my ribs. It hurt! I would mash him feet/hands to make him stop.

I think your uterus is approx level with your belly button at 20 weeks.
Things all get shifted about during pregnancy though, so it could be anything lol!
Sorry, I'm not much help! :)
