Evap?

Can evap be pink in color?  I just know my test has a evap.  I took it this morning about 2 min went by but looked negative we were in a hurry so I through it in my suitcase we were out of town.  Get home pulled it out and there is a pink line.  Grasping a straws lol I know there is a time limit on these things but wishful thinking :) I so feel like af is coming soon I'm just crazy lol this whole process is driving me nuts!! Anyone else feel the same way?
