Pregnant with Gallbladder Issues...Can't keep food down, can't have it taken out!!! HELP!?

I found out I had to have my gallbladder out in July, I was losing weight and having right side pain. Well, on the day of my Pre Op I found out I was pregnant. Now I was supposed to have it taken out at the beginning of my second trimester, but unfortunetly my husband put me on his insurance during open enrollment ( I no longer qualified for my state insurance) and now I have to wait till January before I can have it done, if they will even do it that late! I can't keep food down, I have gained 5lbs none the less since becoming pregnant, but other than crackers, dry toast, and dry cereal etc I can't eat. I sometimes can't keep down juice either. I know in the beginning of pregnancy it is ok to go without much food, but what about now? I am 15 weeks along and I don't know how well my baby can be doing without much food, I do take a chewable vitamin everyday since I throw up the prenatals.........I am so lost, and I don't know what can happen.
