Pcos, metformin, femara

I was diagnosed with PCOS last year after TTC for 4 years prior and a period that came and never stopped. 3 months ago, I finally broke down and went to the specialist, All tests came back okay, so began with 2000 mg of Metformin. Yesterday started Letrozole 2.5 mg for next 5 days... Hopeful this is the month. Any success stories using this mixture? Cycle buddies?
