Hi Helena, I should preface this with the fact my pregnancies were 35 and 33 years ago! I wasn't on any meds during pregnancies as my symptoms were very mild and I wasn't officially diagnosed (with UC) until after the first birth. After the second birth, when all hell broke loose, we tried a sulfa drug that caused allergic reactions for me, then a steroid enema, which necessitated stopping breast feeding. Then I took prednisone tablets, but my flare was out of control. I was losing weight, losing blood and going to the bathroom too often. My doc put me in the hospital on enteral feeding for 5 weeks and steroids by iv, then 2 weeks to gradually introduce foods. I went home for a few months, but ultimately flared again. I had a total colectomy (removal of large intestine) with an ileostomy when my baby turned 1 year. I enjoyed 14 years of good health with no symptoms. I then began having partial blockages of the small intestine, perhaps 1 every 18 mths to 2 years apart. Sometimes I had to spend time in emergency getting pain meds and IV fluids until the blockage cleared. The last time (Oct) a CT was done, then a scope and the docs decided I have Crohn's. Still a mild case. Tried azathiroprine and 6MP, but have severe reactions to both. Not taking any meds at this time, but have been following the paleo diet for 4 months. My stool is quite normal (for an ileostomate) most of the time, so I think the diet is helping my immune system to stabilize. Sorry for the long scary story. If I were you, I'd take comfort from the knowledge that many times the hormonal changes with pregnancy cause the crohn's to go into remission, so the baby has the best environment possible.
