I gotta be crazy.

So my period is 6 days way. I took a test and i saw a vvfl.. i stared at it for a while. i went to go grab my phone to take a pic of it. But i had left it in my car. So i had to go all the way to my car get it n come back. By the time i came back the line was gone. It was past the 3 mins mark. Now i look at and completely white. As if is negative. Idk if my eyes are playing with me or no.
