I can't comment on Imuran, because I'm brand-new to this whole UC thing and so far am only using Asacol and Rowasa. Anyway, I just wanted to chime in about
Taking Charge of Your Fertility. It's a FANTASTIC book! I charted and I thought it was really cool to know that I was ovulating, to know when I ovulated, and to know that we had timed things right in order to get pregnant. Plus, if it had turned out that we were having problems getting pregnant, the charts would have provided my OBGYN with a lot of useful information.
