Can polycystic ovaires go away on its own?

Patient: I was diagnosed with Polycystic Ovaires 4years ago, and I had never had a period, I fell pregnant 2years ago and had a son, then again i fell pregnant 10month ago but unfortunately misscarried,however for the last 3months i have had a period every 28-30days, Is it possible that i no longer have polycystic ovaries?
