Why am I late....Could I be?

Kiara

I’ve been using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> for over two years now. Since August 2018 my period has been coming on the 10th or the 11th of every month since. I didn’t have relations during my ovulation period, but for some reason, Im walking into my 4-5th day late. I am nervous and have chosen to take a test on Friday, when I get paid. But the suspense is killing me. Any advice?
