I'm having really bad rib pain right under my boob. It's almost like having an underwire digging into you but I'm not wearing an underwire boob. It's obviously not the baby because she's still so small, I'm only 22 weeks, and it's on the outside of my rib not the inside. It feels like I should be able to see a bruise or a scratch or something there but there's nothing there. Anyone else having this or know what it's about?
