Help what should I do?

Elizabeth
I've been ttc for 2 years now I've known I had PCOS since I was 11 and was on birth control for 7 years. When I originally started ttc my doctor told me I needed to at least try 1 full year on my own so I could see a specialist. Now that I'm seeing the specialist he sent me to the endocrinologist that started me on metformin and the OB now gave me birth control again saying he wants to "regulate my periods" and says he'll see me again after taking it for 6 months... 
I don't know what to do I've heard so many good things about using clomid and metformin together and being that I've already been ttc for 2 years without BC I feel like its a step I the wrong direction.
