I’m so confused ☹️

So I’ve always had pretty irregular periods. Some months back to back they are perfectly apart but other months I’ll either skip a period or I’ll have 2-3 days of dark brown whatever. We’ve been trying to get pregnant for over 2 years now and so far nothing. I had a gyno appointment last Tuesday and I brought this up to her but all she had to say was “maybe 2020 will be your year” i kinda gave up trying in October, I haven’t been tracking my ovulation a more because my periods are so irregular. I thought I was possibly pregnant becuase my period never really came. I had super light dark brown discharge for 3 days and that was it. I have no symptoms right now and it’s been over a week as well as negative tests. Has anyone ever gone through this? I don’t even know what to do
