 Do I have PCOS?
I know you guys must be saying what am I doing here if im not sure if I have Pcos but I have irregular periods since I was 15 and now I am 18 my peiods started to become irregular since I started to masturbate anyway I went to a gyno last year for my irregular periods and she gave me a requisition form to go do a blood test and a pelvic ultrasound to see if I have PCOS, I did the blood test and the results came back fine but I haven't done the u/s as yet. Can I still have PCOS although blood test came bk nomal?
