Spotting

Hi!! This is my first cycle trying the Mira fertility analyzer. I had an abnormally long period to start this cycle it lasted about 10 days. Then I started testing with mira. I was supposed to ovulate today or tomorrow and when I went to test I had bleeding. And it looks like my hormones dropped in Mira as well. Why would this have happened? I was hoping this month was the month for me but I can’t seem to catch a break.
