I would check with your doctor again before making the final decision.
I had a baby last year, I was in
remission before trying to conceive, however once I became pregnant I felt better than I had in a long time! I had one day where I felt ill the whole pregnancy. I ate popcorn and everything! My good health continued until a few months ago, just before my baby's first birthday, and now while I don't think I'm in an active
flare I'm not feeling as fantastic as I did before (had a few close bathroom calls, that sort of thing).
I continued with my meds (Pentasa and azathioprine) throughout pregnancy and have breastfed while taking them, my daughter seems perfectly healthy and unaffected by the meds.
