hello,
does anyone have any experience with first response brought from amazon?
I keep getting real faint lines on one step tests recently, so ordered first response tests from Amazon. I noticed they already had a very obvious grey looking line before I used it so knew not to mistake this for a faint positive.
do they all have this line, the ones brought from the shop? I'm also confused why the cheap ones are faint positives but on none of the first response from amazon? are they known to be dodgy?
thanks!
