I am 31 years old and 32 weeks pregnant with my fifth full-term pregnancy and have had several gallbladder attacks. I am ready to try the gallbladder cleanse. Which one is the best and safest during pregnancy? Will it start me into pre-mature labor? I've read that some harsh laxatives can start pre-mature labor. Also, should I worry about the toxins being released in my colon because of the cleanse. Will these toxins harm the unborn baby?
