Faint positive or evap line?

Help! I took the test at about 2am. I was half alseep and had set myself up for a neg result so as soon as the test line showed up w/ no immediate 2nd line I got frustrated & just threw the test in my closet which obv I shouldn't have done. Then at about 8am I looked again and saw this. I keep reading online that evap lines won't be pink but instead grey. Anyone have thoughts?
