i would just like to know what the odds are on getting evaporatio lines on several tests of three different brands and two different colors of dye. i took at least 6 equate blue dye tests and a line came up but very faint. i also took two FRER's and got lines but after the 10minute mark. i got faint lines on the dollar store tests as well. what are the odds on that? they were all taken after AF was late and over the course of a week or more.
