PLEASE HELP!!!30 Weeks pregnant, severe abdominal pain presumably gallbladder. Any Advice?

I am 30 weeks pregnant. I told my obgyn over a month ago that I was having severe abdominal pain under my right rib. She told me it was likely my gallbladder and to adjust my diet and follow up in 30 days. Well my pain had actually gotten worse after I changed my diet. I ended up in the urgent care where as much of an abdominal ultrasound that could be performed was. After 8 hours and a ton of blood samples accidentally from my artery none the less they were inconclusive as to where my pain was coming from because they had limited vision from my daugheters positioning. They did how ever find some "good sized" kidney stones. Now, I know that is not the pain I am suffering from, although I am anticipation the page of those suckers any day now. I have increased my fluid intake to over 2 gallons of cranberry and water a day. Try that for a week then talk to me about being uncomfortable... The doctor did not eliminate gallbladder disease, he said I needed to see a specialist and have a more complete ultrasound performed. Little did I know, a urologist wont come near me because of my pregnancy. I am in unbelievable amounts of pain. I was told the baby is more than fine and as long as I can tolerate the pain under my ribs I will be ok. Well guess what. I cant take it anymore!!! It hurts all the time! Im scared to stretch because it kills me, I cant eat because I have no room and it causes sharp burning pains. Im scared its going to rupture. Is there anyone who knows what I can do? I appreciate consolation but I need some serious advice!!!
