Where do I begin?

Hello ladies! 
I have PCOS & I have never had a period without birth control. I go back to the dr tomorrow to talk about trying to conceive now that I've had over 3 cycles on the birth control. My question for you ladies is, "Where do I begin?" 
My insurance doesn't cover fertility meds so it'll all be out of pocket so I'd like to try on my own first, but since I don't have a period without the birth control if I only take my metformin will I still have a period? Am I going about this wrong?
I plan on asking my dr tomorrow but would love to hear what worked for you ladies.
