Idk wth is going on !

Guys I honestly don't know what to think I took the test yesterday and if I don't see something with in the 1st minute I just leave the test and go on about my day ! So I leave my test out for a while and then I come back and I see this faint line I know what an evap looks like but this line is different and the other problem is I don't know if it came within the 3 min mark because I left the bathroom and forgot about it ! WHT do yall think evap??? My period is not due till the 16th wich is tomorrow but no sign of af . I also haven't had time to stop by the store to get a new test ugh
