Quoting merck. "Gallstones appear to be more common during pregnancy. Pregnant women who develop gallstones are closely monitored. If a gallstone blocks the gallbladder or causes an infection, surgery may be necessary. This surgery is usually safe for pregnant women and the fetus." http://www.merckmanuals.com/home/women-s-health-issues/pregnancy-complicated-by-disease/liver-and-gallbladder-disorders-during-pregn.
