Cycle day 11 and already lost hope

I'm only on cycle day 11 but just don't feel good about this month, I've lost all my positive attitude that I had last month, according to glow my fertile window starts tomorrow but if I already feel like this what hope do I have?! Irregular periods, crazy bbt chart, CM I don't understand and negative ovulation tests!! Over 3 yrs of TTC I think it's finally taking it's toll!
