clear blue test

[Pizzax]

hi ladies

I did a pregnancy teat this morning with first wee of the day (6am) and the test showed negative but I only waited a minute (clear blue test which I think requires 3 mins). I saw negative after only a minute and chucked it away. Partially half asleep too as it was 6am! Hours later I checked in the bin and there was a half faint line. (Partial cross) surely this can definitely be an evaporation line but it depends when it showed up as I didn’t wait the whole 3 mins… anyone bad experiences like this? Xx
