It looks to me like you prob'ly ARE diabetic, and are controlling it with diet and exercise. If you had an A1c of 9 sometime in the past, what was the doctor's diagnosis at that time? That A1c would have been a 90-day picture of your hemoglobin - having the flu would not factor into the A1c. That is why I think you could very well be diabetic, but what did the doctor say?
