Re: *UPDATE in OP* Broken rib in late pregnancy = c-section?
Ouch! These are the scariest type of stories IMO. A good friend broke a rib when pregnant with one of her boys. They set it with no anesthesia (UGH) and she ended up delivering just fine vaginally. I'm not sure where in her pregnancy she was when she broke it but she was just fine. I imagine in your case it depends on when you go into labor and how much time your body has to heal that break. So sorry mama. Good luck to you and your home birth and your little one!
