After Not Having Periods For 45 Days I Was Diagnosed

After not having periods for 45 days I was diagnosed with pcos a month ago. After having deviry 10 for 10 days (1 tab daily), period started after 5 days. Since then period did not stopped and continuing for 13 days now with low flow then watery periods after 8 days then suddenly started having clots and heavy bleeding from 12th day. Advised to intake novelon pills (3 months course) to treat pcos.
How do I stop my period alongwith treating my pcos?
