My #2 daughter has CAH, so when I found out I was pregnant with #3, I went on dex immediately and don’t think I slept until I found out she is just a carrier. They took me of the dex (cold turkey) and I was sick as a dog for about a week. Please, if you go off the dex, taper of slowly. When I found out I was pregnant with #4 I didn’t even consider the dex because of my reaction with it. Some people have no reaction, but I’m one of the lucky ones. Best of luck to you!!!
