OPK question

So I just ended my period yesterday, I decided to start testing immediately for OPK and I got a positive OPK for a high LH surge. Is that evening that I can ovulate again that quickly? I normally ovulate between day 14-18. I’m wondering if there could possibly be something still left from period.🤷🏻‍♀️
