Evap lines.

Autumn
Ok ladies I need your help. So I took a test today because AF is due Sunday. I have this habit of checking it after the three mins then leaving it on the counter for a while before throwing it out. Well after maybe 45 mins I went back and found the second picture. Is that just one of those dreaded evap lines everyone's always talking about? 
After three mins
About 45 mins later.
