Did I ever get my positive?

My apologies if I’m posting in the wrong group. But CD 13 I got a BFN opk test as the control line was lighter and then 9 mins later it darkened up and my app picked it up as a peak. I usuallly never ovulate that early and wasnt expecting a peak until the week after so about august 3rd.

Is it possible the test on CD13 was invalid? I’m starting to feel some horniness and my test for today is negative. Yesterday it was high. Did I ovulate on CD13 or was it invalid? I ovulate every month and don’t have any fertility issues.
