I've only ever had one evap on an FRER before and it was from a days old test I found at the bottom on the bin when clearing out rubbish.
It was a clear evap, completely grey and see through when held to light.
AF due tomorrow and have taken 4 FRER the last few days and all have had evaps. They are hard to photograph but have attached the best pics I can get of these.
Bought two packs from different stores but have heard of people having bad evaps on these? Particularly ones from Amazon?
Is there any other pink line tests around that I can try again with if AF doesn't appear tomorrow?
Have taken a Sainsbury's own brand blue dye and it has a faint line.. but I don't trust these tests!
