I'm 5 ft 3. When I was pregnant with my daughter my ribs hurt really bad! Before pregnancy (that time) I was 115 lbs, so I wasn't that large... Maybe that has something to do with it, as there isn't as much growing room in our bodies.
I would still watch this closely & keep reporting the pain. it seems a bit early to be having this.
im pretty short... about 5'2.
hmmm... I'm not sure....
are you a small / thin person? Maybe it is just all the streaching of things?
I would keep complaining. get other opinions.
