Is this dot the start of a line?

I took this this morning and threw it in the trash thinking it was for sure a negative. I didn't actually get enough pee on it either, so kind of just negated it. I didn't think that dot was anything but a speck on the window or something, but now I just got it out of the trash because I was like shit - COULD that have been the start of a line?? What do people think? Am I crazy?? Going to test again tomorrow morning because I'm still 3 days till AF today.
