Temps vs opk

Jessie • Mother of 3 rambunctious boys and loving it! A little girl is hopefully next!
According to my temps I ovulated Monday. But my opk had its darkest line on Tuesday night not Monday. Is it possible I still ovulated Monday? My temps are now rising since Monday. I don't know which one to believe?!? But we did BD everyday so I guess it doesn't matter? Lol aye aye aye
