Soon To Be Mom, needs bowel advice :(

Hello everyone! I am looking for advice from anyone who has taken Cholestyramine aka: Questran during pregnancy. I have Post Cholecystectomy Syndrome from having my gallbladder removed. If I do not take my Questran, I am running to the bathroom with several watery, painful, bile filled stools per day. I am presently 6 weeks pregnant and have stopped taking the medication as everything I read on the internet indicates it is a pregnancy category C by the FDA and daily prenatal vitamins will not make up what you are missing from the Questran absorbing the vitamins from your system. I called the Mother Risk Hotline, out of Sick Childrens Hospital and they indicated it is safe, however, everything online including the information for the medication itself indicates not enough studies on pregnant women but there was potential harm on fetuses of animals. I do not want to hurt my baby but I also know having to run to the bathroom all day is probably not healthy either. It is a holiday weekend where I live (Canada) and I need help until my Dr opens again on Tuesday. Are there any women out there who have taken this while pregnant or did you use a substitute? Hopefully someone can help me.

Thanks! Yes, I go for some blood work on Tuesday... and I will be calling my clinic then. I had my gallbladder removed post first baby.... she is now 13. I'm going to be a Mom again for the first time in 13 years so it is a very exciting time. Pregnancy is tough enough physically not to add the problems with the D, so I want to make the best choices for both the baby and I. I appreciate your post so so much. I can't wait to talk to them on Tuesday to see if there is an alternative. I don't know what I would do if I had a sick baby because of medicine... I'd be very heartbroken and upset I did something to hurt my baby :( hope everything works out ok.
