Which day did I likely ovulate on?

Hi ladies,

So my ovulation test was positive on Monday night (around 6pm) and then also positive yesterday all day (it was darkest on tues afternoon), and now it’s negative today.

I know you usually ovulate 24-48 hours after the first positive test, but does it also matter when it fades to negative or when it is darkest? What I’m counting as my first positive was when the test line matched the control (on Monday night). On tues afternoon the test line was even darker than the control. Today, as of noon, the test is now negative (line is there but fainter than the control).

Do you think I ovulated yesterday when the test was darkest or today when it’s negative?
