I am 25 weeks pregnant with my 3rd child. I have been having bad pain in my very lower abdomin that wraps the whole way around my back. I have tried laying in every position, a warm shower, extra fluid and tylenol. I can't get the pain to lessen. I have had a few contractions but nothing steady or abnormal. Any ideas of what this is or how to help it? Should I call the doctor? I really don't want to be the over-anxious pregnant woman...
