Positive opk after temp rose???

Ja

Hello! So I had a Blazing positive opk yesterday morning. My temp rose significantly this morning. I took another opk test this morning and it was still positive (slightly lighter than yesterday).

My question is, if my temp rose that indicates I ovulated yesterday, why would I still have a very positive opk this morning?

I know ff needs 3 days of higher temps to indicate ovulation , but I'm almost certain that it will say I ovulated yesterday.
