PCOS & Trying to conceive

🌸Maria🌸 • Ttc baby number 1 💖💎 - with PCOS

So guys, I have pcos & was without a period for 10 months. I started metformin a few months ago and for the last 2 months have had periods. Can someone please tell me if this means I’m ovulating? Can I get pregnant? & how do I know when I’m ovulating if my periods are never at the same time every month?
