6MP is a category D drug, but it's my understanding that most of the problems occurred in women who were taking much higher doses than what UC patients do.

The article above discusses the different meds used to treat IBD.
Personally, I'd probably stay on it if I were you and would talk to a high-risk OBGYN before making any decisions. If you do decide to go off of it, I'd switch to a mesalmine drug (both oral and rectal!!!!) and see if you can maintain remission that way.
