plan b question

i know that plan b doesn’t work when you’re ovulating at all, and i know it’s to prevent ovulation. but i always see that plan b doesn’t work after you ovulated. i always ovulate like literally right after my period (literally the next day my period is done), and it usually lasts like 5 or 6 days since my flo app is more accurate than eve. after my ovulation i have my period like 2 weeks after that again. anyway what i’m basically trying to ask is if i take a plan b after my ovulation is finished and within those 2 weeks where the chances of pregnancy is low, waiting for my period, what are the chances that the plan b will work?
