Hi I'm 30 weeks pregnant and have crohns disease. I have been on steroids throughout my pregnancy due to active disease found just as I got pregnant. Over the weekend I felt lots of tightening in my stomach when I lay down to go to sleep. I wasn't sure if these were Braxton hicks or it was my crohns flaring up. Anybody had the same thing or know how to tell the difference? When I have had a flare up in the past, It feels very much like having a tightening in my stomach and I didn't have Braxton hicks in my first pregnancy so can't compare.
