Pregnant test (positive or evap?)

[LRconfused]

Hi I took 2 Tesco pregnancy tests and after the first one a second (faint) blue line appeared after a couple days and I’ve heard this could be evaporation , I then took the 2nd test a few days later and a 2nd line appears again except clearer and darker than the one that appeared on the first test? Is it positive?

Sounds it
Do a digital if you aren't sure

A line appeared after a couple of days??
Disregard that..

How long did it take for the line to appear on the second test?

I would recommend a pink dye test..

The second darker line appeared after no more than an hour and was darker blue but still a bit faint? I have read that evaporation lines are supposed to be colourless but not sure? Was wondering if anyone had a similar experience

Depending on the brand you should discard tests after 10 minutes (or whatever it says on the instructions) and not look at them again as any results that appear after that time are deemed inaccurate. If you are overdue for your period then you should test again and are more likely to get an accurate result with a digital test or FRER

Okay thankyou for the help
