Infertility scare

So.. my period is 46 days late.. I’m scared.. im young.. only 15, and plan on having kids in the future.. is this something I should be really worried about.. My second year of high school recently started up, cOuLd this be because of stress? I’m worried because one of my friends found out she had fertility problems in freshman year. I have no pelvic pain, or anything but google scared me into thinking I might not be able to start a family when I’m older. Usually I’d dread my period but now i wish it’d just come already so I can be reassured.. this is only making me stress more.. please help

Currently my stress reliever^
