Just wondering—lowkey stress

Hi guys, I’m kinda worry because this is my first time taking plan b and I’m just wondering if y’all had the same experience.

So I had unprotected sex w my husband the day before my period was due. On my tracker I’m already ovulated but I still wanted to take plan b. And it made my period late.. still waiting on it (6days behind) has anyone ever experienced this ? I heard it’ll come soon or later..
