Do all tests get an evap line ?

[Damsons]

8dpo and did a test this morning and it was stark white.

i have just checked it again and it has the faintest line, however the line is also very thin, not like the control line. Is it more than likely this is an evap? I will attach a photo but I don’t even think it’ll be visible on the phone to be honest. Definitely a very thin line in person!

If the test was negative this morning, and the line only appeared hours later, you have to assume evap.

recheck in a couple of days using FMU and don’t look at the test after the time it says to read the results by. Hoping you get your BFP 🤞

What kind of test? Was it Tesco by any chance as they are known to be terrible for it.

I have never seen an evap line on any other kind of test I've used such as clear blue or First Response.
