Should I be worried?

Lauren

Okay so I’ve been having sex with this guy for a few months now, and my period is about a week late according to this app. He swears the condoms have never broke or anything like that, but wants me to take a test like ASAP and I plan on it. I’m not on BC and before this year my periods weren’t super regular. Is it possible that I’m just having an off month, or should I be as worried as he seems to be?
