I ovulated CD 20 didn't I?...

Anna
From CD 5 - CD 17 I used the 1st response digital and got negatives, I thought the left line (test) had to be as dark or darker than the right line (control) but the lat two days they seem to be getting lighter and taking longer to show up. So did I ovulate CD 20? I'm CD 22 today, the bottom is the most recent test that I literally took 10 mins ago.
