HELP!!! I am 34 weeks pregnant today and have been having issue sleeping. my lower back, pelvic bone and my whole right rib cage in the back are all painful. I've had the rib pain before and doing what my doctor said to do before. but any other mommas have the same issue and were you able to do anything to help it?? baths and hot showers help in the moment but I want something that will help when I'm laying in bed. all I want to do is sleep but I'm so uncomfortable. :(
