Hello! I am 3 and half months pregnant myself and was in remission and one week ago I just started flaring with urgency and blood. So I use cortifoam enema alternating with salofalk suppositories throughout the day and at night I am currently using hycort enema. Plus I am still taking my salofalk tablets daily. My GI said they are all safe during pregnancy and I also double checked with motherisk hotline and they do the research and ok'd them all. Plus I just increased my probiotic intake to 150 billion active cells per day. Its been only a week and things have improved already hopefully with all the probiotics I'm taking symptoms will decrease in the weeks ahead.
With my first child I flared during the whole pregnancy but never new about probiotics they make a big difference. Try to get things under control now because I know how bad things could get during pregnancy with a flare happening.
