SheilaDawn,
Sorry to hear of your miscarriages. If you are taking an informal poll, I have SW-CAH and have 4 children. I’ve never had a miscarriage.
I’ve been told miscarriage in the general population is actually quite common, especially in the first pregnancy.
My mother, a carrier has had 3 miscarriages. My sister (non-CAH) has had two.
Don’t know if this helps.
Good luck!
