After an hour?

Sarah
So I took an .88 walmart test, AF is due in 4 days. It was negative, but then I peeked after about 45 min and saw this? 
My only hope is that I always peek. Like the take it out of the trash kind if crazy... And I've never had one change color before. On a scale of one to 10 of nuts am I to have hope that this could be it.
Also my toothpaste tastes like pennys... So that's something? haha.. I'm loosing my mind! Thanks glow!
