My husband and I have been starting to talk about having a child.  At the age of 23, I finally went to an endocronlogist about my hormone problem that I have had my entire life and found out that I have CAH.  Currently she has me on Predisone, a cortisol hormone, to keep all of my hormones at the correct level.  Every six months I have a blood test done to make sure.  Does anybody know if it is OK to take a cortisol during pregnancy to keep the hormones at the correct level?  Do you discontinue when you become pregnant? Will it cause birth defects?
