Positive or Evap?!?!

I took a test about a week ago and it showed a vvf line. Well since af is officially 2 days late I decided to take another test. Another vvf line showed up but a lite darker so I just sat it aside. Well just a little bit ago I decided to double check to make sure I wasn't seeing things and the line has gotten darker. In the photo it doesn't look like it has color to it but in person it does. I just want some other opinions before I run out and by a more expensive test. I've been having a lot of discharge since Monday also, thanks
