Just trying to get some opinions on this. Is this an evaporation line?? My period was due today and hasn't come yet so I took a test this afternoon, it was negative right after I took it so I left the washroom forgetting to throw it out. Went back in an hour or so later and saw the faint line. I took another test immediately which you can see in the picture that it's negative. Please help a mama out! Thanks ladies.
