Long cycles, bbt looks crszy, ovulation happening?

Hi all, since the last MA last year in May my cycles have got as long as 42-53 days. Im already in runni g different tests and we are now trying to shorten my cycle, but thats not the story.

Today was my 27CD and I had actually a t* dip 2 days ago on 25CD. Today, finally seems like I got my peak (according to 3 apps), so Im now wondering- could it be that my t* dropped 2 days prior positive OV test? Its first time I got it positive!

Normally they say that the drop is on the day of positive OV test, but it doesnt seem to be case.

Am I really gonna ovulate?
