3 lines?

Tiffany
I took a pregnancy test strip today and it came back with 3 lines. The line on the negative mark was bright. But where the positive lines suppose to be there was 2 faint lines. When my husband got home an hour later I showed him the test and the 2 lines are gone. It's a very faint line in the positive mark so faint it's hard to see. What do you girls think it is?
