I took a test this morning and it had a faint but visable line, it seems to have gotten darker during the day which has made me question whether or not it's an evaps.
I took another test on a 2 hour hold in the afternoon and it has a line in the same place but fainter.
I have ordered some cheapies which should be here tomorrow but i don't want to get my hopes up if the asda tests are bad for evaps or false positives.
