PCOS advice!

Caitlin
I've been on progesterone for 3 cycles now and haven't concieved. The "fertile days" glow predicts for me end up being wrong when my period comes, so I end up with a lot sex during the wrong part of my cycle. 
I'm confused on how to know when I'm ovulating or not, if I even do. 
I have PCOS and the progesterone was my doctors first attempt at getting me pregnant before she tries clomid. 
Being as I have PCOS the opks aren't a good choice, according to users on here but I just need advice from someone who's been on what I have or had PCOS.
