AF was due Feb 23rd.. Still no period!

Skylar
My name is Skylar, my period was due almost a week ago I still haven't got it. I'm like terrified to test. I don't really know when I should, I want a accurate result so I don't have to keep repeatedly taking tests. I have some symptoms but I don't really want to rely on that. So any advice on when I should take a test or what I should do??
