no period. not pregnant.

Jo
I haven't had a period since September of 2016. Before anybody assumes I'm pregnant, I'm not. I've taken so many tests and I went to the doctor as well. She took a blood test and sent me to a endocrinologist. He said everything is fine on his side and my next stop would be at a ob/gyn office. 
I was just wondering if anyone else had a similar situation.
