I was in 100% remission and have relatively mild UC, but I had the worst flare of my life when I was 6 weeks pregnant. I used hydrocortisone enemas daily for 2 weeks and got my flare back under control. I continued with Rowasa enemas throughout the rest of my pregnancy and was 100% back in remission(I was even constipated for a while..now that was a weird experience!). I didn't flare again until I weaned from breastfeeding and had to go on Asacol to get back in remission. My advice is talk to your GI. You don't want to miscarry because of your UC. You need to get it under control, even if it means more meds. Ask about
the hydrocortisone enemas..they worked for me. Try different things and give them at least 2 weeks to kick in. For me the pregnancy hormones in my 2nd and 3rd trimesters actually helped me maintain remission, so it might be the same for you. Good luck!!
Officially Diagnosed with UC in June 2003. Have had stomach issues since 1989. Unknown if they are related or not. Have mild/moderate UC. Have had 4 flares, the last one caused by hormones from stopping breastfeeding. Currently back in remission! Only taking 6 Asacol a day. Will take Rowasa enemas as needed. Colozal did not work for me. Luckily my UC is relatively minor and responds well to meds, but man do those flares hurt!
