Positive or Evaporation Line/Faulty Test

I have a very strange situation. AF should be coming tomorrow. I tested with a dollar store test yesterday (Chtistmas Day) and it came out Negative. 
I tossed the test in the trash and didn't think of it until I threw away a piece of trash this morning. The test was on top and had a pretty dark colored pink line indicating positive. I had already had my first morning urine, but grabbed another test and tested again. (The urine wasn't very dark) I ended up with no line.
I'm feeling very fatigued and had a slight pink tinge when I wiped earlier. No more pink, even if I slightly swap with a q-tip.
What's going on here?
