Ttc nightmare

Currently an absolute nightmare. I’m on day 60 of my cycle and have had 4 cycles without ovulation. Thought I had high prolactin but then didn’t, now blaming it on the fact I’m slightly overweight (yes I know this is a factor and i’m trying) I have PCOS and was diagnosed in 2014 but we just don’t seem to have any luck. I’ve been on Metformin twice a day (500mg) for a year and still nothing. Anyone else feel like it’s just never gonna happen? I’ve got an appointment with the gynecologist tomorrow morning.. anyone has this experience? And if so what’s usually the next step?
