ve had it a few times.. it was a very deep chest
cough - meaning that it felt like i had to
cough and
cough to get anything to come up.. - unfortunately, with that much coughing , and being pg, - with pressure from the baby, it can feel like a rib is broken.. be careful tho, my bronchitis turned into pneumonia.
if your back/ ribs hurt that much, go to your doc - coughin with pain in those areas are a common symptom of pneumonia..
hope you feel better soon!
