Can you come to her next appointment with us?  You’d be a great one for him to hear this from...... I know I can explain why but I am not sure I can explain the rhythm method if he doesnt already know what that is.  Thats scary huh?  Well, I think he treats more diabetics and growth hormone patients than anything else, although his nurse assured me he does see others with CAH.  I will keep you posted. Thanks.
