Hi, I am 18 yrs old. I have PCOS since the first time I got periods (in 2008)I recently had my ultrasound which showed that my Ovary size has reduced,however,PCOS is still there. My last period was in March and its almost September. This has been the longest time,should I take medicine (deviry 10 mg) to induce it? I am also confused that if my ovary size has reduced and i am getting better, why have I not got periods for so long?I had stopped taking medicine 2 years ago.
