SherryHi Joanne,
In my opinion, I would take the dex. You may or may not have to take it very long, and I really think the side effects (and you may not experience any) are worth it even though they are hard to deal with. I would rather take the dex and not have to have my daughter go through the surgery then not take it and have that added stress for her and for our family.
It’s really up to you, if you feel you would rather have a girl and not take the dex, then that’s your decision. :) Just make sure you meet with a Genetic Counselor to talk about CAH, taking the dex and anything else you might need to know. They are very helpful.
Take care!
Sherry
