Gallstone pancreatitis during pregnancy

Anyone else have gallbladder problems during pregnancy ? This is my second gallbladder attack in a month. My gallbladder has never affected me before this pregnancy. I changed my diet to low fat after the first attack. With the risks of being pregnant they are refusing to do surgery to remove the gallbladder or the stones via endoscopy. So I am stuck with this until I deliver my baby. I will be 31 weeks tomorrow.
