You should be checked out every 4 to 6 months. If this is not feasible, go based on how you feel. If you feel run down all the time and have muscle weakness, pay whatever it is and get checked out.

DO NOT BANK ON CAH PREVENTING PREGNANCY!!! I have Salt-wasting CAH and I have 4 beautiful children.

At the very least, your children will be carriers of CAH. If your partner has CAH, they WILL have CAH. If your partner is a carrier of CAH, each child will have a 50/50 chance of having CAH or being a carrier.
