Hello!!  I started Dex when I was 5 weeks along.  I believe I was on 1.75mg a day.  It was 4 years ago, so I don’t really remember.  I had a CVS when I was 10 weeks along.  The next day we found out that we were having another girl (I have a 6-year old daughter with SWCAH), so I had to stay on the Dex until we found out whether she would have CAH or not.  Around 16 weeks we found out that she did not have CAH, so I was weaned off the Dex.  It only took a week to get off of it.  I was very moody on the Dex.  I had a short fuse so to speak.  I would freak out over little things.  It seemed like I was always hungry, and be prepared for stretch marks.  After I went off of the Dex, all of these things went away, and I felt "normal" again.  It doesn’t happen to everyone, but this was my experience.  If I had to do it again, I would. 

Congratulations, and I hope you have a great pregnancy!!
