Last night i went to bed with severe upper right side rib cage pain. I don't know how t happened all i know is that it freakin hurts!! I was wondering if the stress of being in pain could start labor? I'm 35 weeks 3 days. This pain is terrible, should i get it checked out? Call my dr? I don't want to go to the er and have them tell me there's nothing they can do since I'm preggo :( you ladies have any ideas on what i should do?
