Sainsburys Test - evaporation line or BFP?

[user1471874092]

Did a Sainsburys test mid morning, was negative.

Looked at test again (4 hours later) and it now shows an obvious blue line.

Did a Clearblue digital test and said 'Not Pregnant'.

AF due in 4 days.

Are evaporation lines blue? I thought they would be grey?

Has anyone had this happen to them?

Thoughts? Am so nervous?

If the line has appeared OUTSIDE the time it tells you on the test eg 10mins later then the result is to be discarded.
Try again in 2 days but if this line was not there in the outlined development time then appeared 4hrs later it's an eval

Try a first response test

What colour are evaporation lines supposed to be? (I thought they were grey?).

This line is showing up as very blue....

I'm pretty sure they are grey. I'd try a pink dye

I've had blue evaps before! I wouldn't trust anything after timeframe now. Hope you get your BFP in a few days

Yes had blue Evaps from the use a first response first thing in the morning and read within the ten minutes.

So disappointed, the line is actually blue, will test again tomorrow...

Best to use pink dye tests, first response are good

Hi Ive just done a Sainsbury's test I've got it come back with the round bit with a dark blue line and the long bit with a light blue line am confused as I throw away the book am just wondering please helpb

To be honest your line is more to one side than in the middle and it does look quite thin. Although I don't have experience with these tests. Good luck x
