I had this pain for the last four months of my second pregnancy and it started again this week. I just had a gall bladder scan today and am waiting for the results. It is sharp and constant pain under my right rib and goes around to the right side of my back. No nausea or other symptoms, just pain. My guess is this is being caused by my baby putting pressure on the gall bladder, the pain stopped in my last pregnancy as soon as my son dropped and I never had it again. Just wondering if anyone else out there has experienced this.
