Stupid question

I took a pregnancy test yesterday and thought maybe I saw something but it was way to faint tell but I took a glance at it this morning because I forgot to throw it away and there is definitely a line. I know at this point the test is invalid and its probably an evap line but I've 1 never gotten evaps before on these test and 2 I kinda think I saw something in the time frame.

So my stupid question is have you ever gotten an evap line and turned out to actually be pregnant?
