Polycystic ovaries with normal bloodwork

Maddie
Has anyone had polycystic ovaries but bloodwork is normal? I also have irregular periods. 
I am looking for something to help regulate my cycle...
I've heard of people with PCOS taking Metformin but is it just if you have PCOS due to insulin issues?! 
My doctor told me birth control but I don't want to take birth control.
