I had gallstone attacks when I had my third child.  It is no fun, but after I had the baby I never had any more attacks for about 15 years.  Then they started again and I had my gallbladder removed.  I have heard of many women while pregnant having attacks, she is wise just to try and control them until after and wait and see what happens.
