I am not pregnant but I was having pain in my gall bladder. My ultra sound showed no stones. My chiropractor put me on a good digestive enzyme and choline. My pain finally went away. I did notice that a fatty meal made it flair up. Some people swear by the olive oil/lemon juice cleanse but with stones, I don't know that that would be advisable. Another route might be to go to the health food store and see what herbs are gall bladder specific. Good luck with your search.
