I flared during my pregnancy in 2006, mostly during my 2nd trimester, which required prednisone, but I got a lot better by my 3rd trimester..my dr. said the hormones change a bit then, which might have been it. I was fine until about 3 months post-partum, when I started using Rowasa enemas to control a flare, but ended up back on prednisone. Unfortunately, I did not respond to pred. well, and made the hard decision to stop breastfeeding when my daughter was 8 months old to go on Imuran. This drug really helped me a lot, though I am uneasy about contemplating another pregnancy in the next couple of years on this drug. Just do the best to take care of yourself, eat the best you can, and stay active if you can as well. Couldn't hurt to see a nutritionist to make sure you get all you need right now, I used to get headaches from eating too much or too little of some foods. Good luck with your pregnancy and keep in mind you might very well have no problems at all.
Diagnosed with UC in 2004
Had flares all through pregnancy last year, and current flare on and off for about 6 months, Imuran helped me get off Pred. and get into remission!!
Currently on Lialda, Imuran 75mg,
prenatal vitamin(taking for folic acid and other nutrients), calcium, and Bifidus Balance FOS probiotics.
Mesalamine enemas as needed...
