Which is my peak? 😭

Hey guys.

This is my first month tracking ovulation, using amazon cheap one step tests. I’m a 28-29 long cycle. Had the mirena coil for 6 years, removed end of April. Periods had already returned before removal, and after removal it didn’t alter it in any way, apart from first one being heavier in comparison to cycle before removal. But i came right on schedule two weeks after it was removed.

So I assumed my peak was around day 9 or ten, as after that as can be seen on pic they began getting fainter, yesterday was super faint. Then today looks very much like a peak.

I’m so confused. Can anyone shed light/advice on when my peak was? I’m currently on CD15, period ended on day 3.
