Clear Blue +/- evaporate or positive?

[CardiBardi]

I poas this afternoon, AF due but feeling really dizzy and sick. Used a clear blue (not digital) test and the second line came up within about a minute, but it seemed to be grey rather than blue.

I know CB are notorious for evap lines - but could it be evap if it comes up so soon? Or is it more likely to be a bfp?

I haven't got a photo as I was at work, and stupidly put it in the bin after staring at it for ages

The standard mumsnet advice is still the best- test again tomorrow w FRER with fmu (first response early response with first morning urine) You can save your first wee of the day is a cup or something till you can get the frer.

Good luck!

Yes I definitely will test again tomorrow.

Just wondering how likely it is to be evap or positive. Driving myself a little crazy! 🙈😬
