faint lines but Digital of that negative?!?

Katie • ♥️🌈💍
I posted last week about my faint lines. Over the weeekend I thought it would be a great idea to do a digital test which came up "not pregnant". My AF was supposed to come yesterday and it still isn't here. I don't know if I should keep testing or just wait it out. My husband wants me to take another test. I'm just lost I don't know if i should test again. 😐
