Plan B stories

Hello! I took plan b on December 28th which was the last day of my period. After a few days I had bleeding for about a week. My period was supposed to start about 7 days ago but nothing yet? I do plan on taking a test soon to be on the safe side but wanted to hear if anyone had similar situations! I have also been stressed about a few life changes, plus the pill in the first place, so stress could be another factor.
