Faint line between 3-5 minutes?!

I'm trying not to freak our because we've been trying to conceive for Years....I was sick the last few days with nausea and vomiting, thought it was a bug because I felt better today. Took a pregnancy test just in case, and when my husband checked it later he saw this. HOWEVER, I am hesitant because the test said don't read results after five minutes and he's not sure if he saw it before or after the 5 minutes. I'm about 4 days away from my period....

Don't give me hope yet....but I've never seen a line, even faint, after five minutes?

Anyone know the difference between an evap and a positive??
