Hi! I Was Diagnosed PCOS Last April. My Doctor Prescribed

Hi! I was diagnosed PCOS last april. My Doctor prescribed me yaz and metformin for birth control for 3 months so I can regulate my cycle. Then after three months, she prescribed me clomid (50mg 2x a day) for 5 days, premarin (1 tab 2 x a day) for 20 days and duphaston (1 tab once a day) for 14 days. But I took already 2 months I still did not conceive.. Should I still take it since I still have 1 more month of medication?
