pregnant! positive test one week before missed af???

I think I'm super pregnant!! I took this this morning and I'm not expecting AF until exactly one week from today. Is that even possible to have the test be so strong one week before your missed AF??? My husband and I decided to relax and take a break from tracking!  Sorry it's blurry I was shaking a ton! The lines popped up within seconds! Is this normal??? One week before??? And this strong???!!
