I was diagnosed with PCOS last month and my doctor has prescribed me Diane 35 and a herbal medicine Diaherb. I am taking these medicines and I have finished one packet of Diane already but still having no periods. It's been a week since I have finished the pack of Diane. I am having dark brown spots only from 6 days but no periods. Kindly guide me if its normal and when should i start the new pack of Diane 35 now?
