HeatherCongrats!
I’m pregnant with our 3rd right now. Our oldest has CAH, our second doesn’t. My son sees a fantastic endo at the University and when she heard I was pregnant (the last time) she informed me that I needed to get on the DEX asap. Same thing around this time. Since your baby’s sexual organs are forming already, he/she needs all the help he/she can get! I don’t know how comfortable you are with "bothering" your doctor, but I would try talking to him/her again...
Good luck!
