Disappearing line?

Hi ladies!

I went to the market today and the only test they had were these cheapie blue dye tests (I know, the curse!). I took the first one and a line immediately showed. I ran to the other room and decided to take another. Both came up with faint lines. When I went to go show my husband an hour or so later, the lines were lighter or had almost completely disappeared. Would you say that it was positive?
