Just found this post and am very interested in the FMT.
I had Crohn's since 2008 and this last year has been very bad.
I have been on Steroids (Prednisolone) for 8 weeks this last november and december, (didn't want to go through this but didn't know about FMT at that time)
I have appointment tomorrow for a new treatment and will ask about FMT.
but I have a question... I'm 5 weeks pregnant, I don't think FMT would cause any problem to my pregnancy but I'd like to know if anybody as been or is in the same state and what they do. the pains are horible !! I have been warned that being pregnant while having Crohn's can be very painful and I agree to that, but planning or not a baby does not always work !!
I don't see that anyone answered your question so:
If you have a healthy enough donor then FMT should be only beneficial for you and your baby. The healthier you are while your baby is growing in you, the healthier they will be.
However, an unhealthy donor could be harmful to both you and your child.
Doctors won't do FMT for anything other than c.diff, so for Crohn's you'll have to find your own donor (which is the limiting factor for most of us). There is lots of info on FMT in the last link in my signature.
