Momma Rolz get to a good chiropractor or massage therapist! Read the book "The Other Side of Pregnancy" by Dr. Trenton Scott on back pain while your pregnancy. Just search Amazon.com. It helped me a ton with my third child. There is a story about rib pain in the book. It will litterally take a chiropractor five minutes to fix your problem.
Thanks Tina2225! I will get the book and read more about it. I went to the chiropractor 3 weeks ago and it helped me tremendously. Good posture does help but with my growing belly, the summer heat, and tiredness, it's really hard to keep the posture. I always tell myself - 2 more months!!!!
