Late Period After Taking Plan B

Hey so I’ve been on the pill for about 8 months now, rarely if ever missed a time to take it and my periods have been very regular ever since. Saturday my boyfriend came in me and though I’m on the pill and my period was supposed to come this Wednesday, I decided to take Plan B just as an extra precaution. Well my period is 3 days late and I’m growing concerned. I know that Plan B can affect your period being late or early, but you never know with these kinds of things. I was wanting to hear anyone else’s stories related to this to ease some concern. Or if anyone has some recommendations to make my period come or as to what actions I should be taking. Thanks♥️
