Evap or no?

I took a dollar general brand test this morning, at 3 minutes I thought I seen a line, but then I looked more like a thick white line. But it kept becoming noticeable. At 12-13 minutes the line looked purple and thick. Evap or no? I want to wait a day or 2 to test again.

1st one is 3 minute mark. (Can’t really see what I seen in a picture)

Pic at 12-13 minutes
