Why Am I Getting Periods In Every 2 Months?

Hello, I was prescribed Dronis 30 to regulate my periods as I was unable to conceive even after trying for 8-9 months. However, I have completed the 3 cycles of taking Dronis 30 and my periods have got even worse. I get periods every 2 months after I stopped taking Dronis 30. I am even more worried as we are trying for a baby now. - Janvi
