Polycystic Ovaries & Not Ovulating?

Maddie
My doctor did an ultrasound & I have polycystic ovaries. I have had irregular periods & am not ovulating on my own. 
The doctor never confirmed PCOS. He just told me about the cysts & explained I'd have to be on BC when not TTC & Clomid if TTC. 
I want my period cycles to be regular! Any advice?! 
I have heard of Metformin, but I've also heard you can only take that when you have PCOS due to insulin issues. Is this true?
Thanks ladies!
