Bfp or evap

So I read that to get rid of an evap that has color you put water on the test where you peed & it washes it away. I did it & there's still very much a second line and it's pink. I could actually see the water washing on the screen too so I know it got washed. I want to know if it could still be the evap or if it's an actual bfp? I posted a picture on here earlier of my test and everyone was saying it's an evap ..
