PCOS & regular periods

I’m creeping in on month 10 of ttc our first, and I am just emotionally and mentally miserable. I just don’t understand why. I feel like a failure. I feel broken. I haven’t seen a positive opk. I just don’t have the heart to track bbt yet. I’m trying to be positive and enjoy this journey, but I didn’t anticipate to be so miserable.

I am trying to not symptom spot every little thing, but I got to thinking maybe PCOS? I’m hoping to discuss with my doctor later this summer. I have some signs but I doubt it because I have regular periods. Just wanting some insight from those who have PCOS and regular periods. What were your symptoms? What testing and bloods did you go through?
