First Response White Line

Hello,
Ok I might be crazy here looking at a white line on a First Response Early Detection Test.
It's 3 days until my expected period.
I took this test this afternoon and this almost glimmer white line appeared. I've never had it happen before. Could it be a fault in the test?
It was tricky to capture on my camera.

I don't think a white line is positive. You see them sometimes if your urine is pretty concentrated and it slightly changes the colour of them test stick everywhere except where they put the chemical to detect hcg (the pregnancy hormone). Also if you left the test for a bit evaporation lines can appear white.

Personally I'd just wait a few days and retest as then you should know for sure what it means.

Sorry!

Also just adding I can't actually see the image you've posted.
