AI don’t know whether it’s CAH or not but one thing I can tell you; don’t let the doctor decide over the phone that you are having a miscarriage and that’s the end. If one doctor gives up hope go see a high risk O/B GYN. Maybe there is still something you can do to save the baby. Often there is an underlying reason and with proper bed rest and good treatment you can still save the baby. One thing to consider is, where you feeling nauseous and tired lately? A too comfortable pregnancy can often be the first symptom that all won’t go well.
Good luck
