I have PCOS too and now I have a gorgeous 3 months old little man.
I've been taking contraception (the pill) for several years for helping with the PCOS. When we decided get pregnant, stopped taking the pills and my doctor recommended start taking Metformin - which is used for diabetes issues and I'm insulinoresistant.
I got pregnant after a month of stop taking contraception.
As its been +1years you've been trying, I would recommend you to go to your doctors as they will help. Hey might make you a scan in your ovaries (they made me one to confirm I had cysts in my ovaries).
Also, apart from the medical/technical bits I would recommend you to relax. I understand it might be difficult and having PCOS can make you think you're unable conceive and this thoughts can bring you down and make you feel guilty and bad with yourself. I've been so scared for many years thinking I could never have children and carried loads of anxiety. Rely on your partner as this is something that both of you will be doing.
To sum up, as with PCOS is difficult to know when you're ovulating, so I won't recommend to use ovulation tests, etc. I bought a saliva test in amazon called Ovotel and worked perfectly for me and is very easy to use - I cannot recommend it enough!.
Hope this helps! As I cannundestand perfectly your frustration.
Best of the better wishes!
