I just came across this post... last Thursday I did one of the new sainsbury's one's with the blue cross. After the time limit (and I know not to look), there was a faint blue line. I took another one on Saturday morning, FMU, and a faint line came up within the 10 mins. It actually came up straight away and then faded a bit but you could clearly see it although very, very faint before the 10 minute mark.
Now, I've read a lot about blue dye tests and evaps. So i thought I'd test my last one with water - I'm not mental, lol - I just wanted to see what happened as it dried. Anyway, no faint line, no evap. Anyone else tried this?! Or am i the only weirdo!
I'm waiting til tomorrow and will do another.
Personally, and not to upset anyone but they do say a line is a line and if you get a +ve result before the time limit, followed by -ve tests... I would say thats a missed miscarriage, i'm sorry. I've had 4 miscarriages, sometimes I wouldn't even get a +ve urine test.
