So I've caved and taken a blue dye I wasn't going to but hubby picked wrong one up whilst in shop. I took it out the casing before any bashing (I know your not supposed to take much notice and they are "classed" as invalid when out the casing but the glare from the light was on the control screen and I just needed to show you ladies what I was seeing for your opinions as I'm sure I have a very faint positive slightly blue coloured second line that's appeared. What do you think? Honest thoughts. I still plan to test again in the next few days using a FR just to be sure
