You might be able to wait for treatment till after. I also had my gall bladder out before pregnancy. Try not to eat a lot of fatty foods abs drink plenty of water and talk to your dr for alternatives. Good luck!
I have had my gallbladder out but not during pregnancy but i know a few women that have had it out during pregnancy and never had problem..it shouldnt effect your baby but speak to your doctor about it and the best course of action..good luck..its a horrible pain to deal with it i know
