So I took a pregnancy test yesterday (last night

) and when I look at it I though BFN all the way. The one line was so dark so clearly I'm not pregnant...well I looked at the test again today and there was the faintest of second lines, like I really have to look hard to see it. Not sure what to make of this. I bought the three pack of tests so I plan on testing again in the morning (AF is due tomorrow). Anyone have this happen and turn out to be pregnant?
