Ovulation question

The first picture is of a strip I did this morning. You can see the test line pretty clear. This strip was the darkest line I've had so far all week. It is not as dark as the control line so I assumed I was not ovulating just yet. I took another test just now, it is late afternoon, and the test line is barely there. The second strip is the second picture.

What does this mean? I thought this only happens after you ovulate 😕 was the previous line me ovulating and now it's over?

Thank you
