Hi, I am 8 weeks pregnant, 40 lbs overweight and having terrible nauseau. I think I just had my first gallstone attack. Went to the ER and they did bloodwork which indicated Gallstones but they could not find any on the ultrasound. I would really like to prevent another attack, but I am certain I do not want to have surgery while pregnant and would really like to avoid surgery altogether. Are these cleanses safe so early in my pregnancy? Are there other methods I can try to pass the stones?
