Doctor, I’m 32 years old and have been suffering from PCOD  for around 20 years. I have tried different treatments, along with diet and regular exercise, but my periods are still irregular. Last October, I had continuous bleeding for 30 days. After 6 months of treatment, my scan showed no PCOD and my periods became regular for about 3 months. But for the past 4 months, my periods have become irregular again. I had a scan 2 days ago, and the doctor said PCOD has come back. I’m very worried. Why does this keep happening even though I follow a healthy diet and exercise? What medicine wil help to get regular periods continue to use.
