I got my period and feel defeated

I did ovulation testing for the past couple months and BD as planned (twice) after the surge was detected. I was excited and optimistic, but then I got my period today. I was devastated. I feared so much that I would have complications TTC because my periods have the tendency to be abnormal. The few months they were regular around 32-33 days, but they have fluctuated as high as 44 days (only like once a year). I am scared of how difficult this road to pregnancy may be for me. Any words of advice?
