My (twin) sister and I also have CAH, couldn't tell you exactly which form however. We are 20 year old sophmore's in college. Our endo put us both on birth control pills so we could have regular periods. My sister is for the most part unable to have a period on her own, and had them fine on the pills. I have some periods on my own, but they are very irregular. Our endo first tried the drug Provera on us to see if we would have a period at all, then when we were ready he started us on the birth control. It has worked for both of us, so I suggest that you see what your doctor thinks. I hope all goes well for you! Good luck
