Just need reassurance that i'm not

Sorry for the most likely stupid and obvious question but i suffer from anxiety and paranoid thoughts! So i really just need someone elses input to soothe my delusions. I haven't had unprotected sex the only thing going on is my period is 7 days late and it's never been more than a week late (though i have been super stressed due to job interviews this week) the one on top was taken today (7th day using first morning urine) i'm not pregnant according to these right?
