Late period

I know this is the stupidest thing to ask opinions about but I'm like weirded out at the fact that my period isn't here (I haven't been sexually active since like forever and I am currently not seeing anyone or having any hook ups of any sort ). l get my period every month and on the month of June I did not get it, I was supposed to get it around the 27th and have not gotten it. I am just wondering if one of you ever felt stressed out about not getting your period eventhough there was no way that you could be pregnant
