Positive OPK and temp drop?

So been testing with opks and Tuesday it was negative, Wednesday it was a high blinking smiley, and yesterday a solid peak smiley (all taken at generally the same time each day) I also check my  BBT (also same time each morning) and my temp went back down today😕 meaning I didn't ovulate when the test showed positive? Since you need three high temps to confirm ovulation. I'm confused at this point since my temps always peak and opks always been spot on. Anyone else have this happen before?
