Bbt confusion

So I am on cd9. I did not temp through AF for the first time ever this month. I ha a few low temps and then the last 2 days have spiked super high! ...the kind if temps I get well after Ovulation high. I turned the heat down last night seeing if that had anything to do with it, but my temp was even higher today. My coverline is ALWAYS below 36.5 before O. Last 2 temps at 36.59 and 36.61..: what's happening?!
