Trying to be hopeful

I just took a pregnancy test and got a BFN. I’m due for my period tomorrow; and this was my 5th cycle trying. My cycles have been so long lately, this month will probably be 40 days, last month was 36 days. I’m 32, healthy BMI, exercise regularly, and generally have a great minimally stressed life and I’m deeply in love with my husband. It’s getting me upset that this is taking so long. Any words of encouragement or positive stories would help.
