Positive opk

If I have a positive opk for 2 days in a row does that mean I haven’t ovulated yet? I got a positive yesterday and still having positives today. Once my opk turns negative is that when I know ovulation occurred or does that mean it’s about to occur?

And yes I know just because I get a positive opk doesn’t mean my body is releasing the egg. I’m also temping. Just trying to figure out how long I should keep BD
