?????

Has anyone gotten pregnant from an evaporated test? I felt like I saw a very faint line, put it away and checked it the next day and definitely saw a faint line. Looks as thick as the control line. Haven't tested again, but I'm just wondering if anyone else had the same situation before. It's been exactly a month since my period ended and I still haven't got it yet but I did have a chemical pregnancy during the end of june...
