Evap, negative, invalid???!!!

Lou
Please read all.
I am 9po. This was first morning urine. The test was negative during the time span. 
Forgot it on the counter, went to work came back home to a semi dark pink evap line. I read that if you ran it under water, if it still stays pink then it's a possible positive. Which I did for a minute. The results after running w/water is the photo posted. 
Can evaps ever be pink?? Anyone experience pink evaps before?? 
My evaps have never been pink but gray.
