Help! Results of pregnancy tests

[Shanice1]

Hi, I'm just wondering if anyone can help. I took 3 clear blue pregnancy tests. First one came back pregnant 1-2 weeks then I took another a few hours later and it came back not pregnant. I then took another one in the morning which came back not pregnant. I was so confused as to why the first one came back positive so I took 2 more tesco tests. Both came back with very faint line which I'm thinking is an evaporation line?? I'm also 12 days late.

How long did it take for the lines to appear?

Congratulations!! I think they are both faint positives, not evap lines. Don't think you can get a false positive, but you can get a false negative. Exciting!! ☺️

they look positive to me. that's 3 out of 5, i'd err on the side of pregnancy.

Different tests have different sensitivities so it is possible to get a mix of positive and negative results.

Pink dye tests, like Superdrug own or First Response do not suffer with evap lines as frequently so are a bit more reliable.

The lines appeared after about a minute, thank you for your replies. Still so confused about it all, think I'm going to take another test in a few days just to make sure!!

Also remember that, in the early days, you may have less hcg in urine that isn't fmu.

Definitely positive - there is colour in the line/s

You're pregnant. Evap lines are white of grey. The blueness means you're defo pregnant.
