Disappearing line on frer

[Kieferzz]

So confused and aggravated. I held my pee and went out and bought a three pack of frer. A faint line showed up almost immediately and stayed till about the five minute mark and then it faded to a bfn. It says to read at the three minute mark in which there was a line there but then it says not to read after ten and the line faded before the ten minute mark. Anyone else have this?

disappearing lines generally are a type of dye run. Keep testing though and good luck.
