Hi Joanne,  I made the same decision as you, after all there is only a 12.5% chance of the baby being an affected girl with CAH, so therefore an 87.5% chance I would be taking dex for a baby who did not need it.  As you say, even with the 12.5%, there were no guarantees and unknown consequences for any baby, as well as myself (although I would have been prepared to accept these, if I was assured the baby would benefit).  I was fortunate that my second baby was not affected, so do not of course regret the decision but like you would have accepted whatever the outcome, having made that choice.  I am pleased to hear both your girls are doing well and agree, it will be nice for your girls to have each other to confide in.

Would I make the same decision again, should I decide on having another child?  Difficult to say, it is not an easy choice and there is no right or wrong one.  Doing research and deciding what is right for you at that moment in time, is vital - no-one can make the decision for you, you must follow your instincts and stick with it!
