Is this a evaporation line?

[SCHK2022]

I have used the Clearblue Early Pregnancy Detection 12 dpo, and my last period was 24th Dec.
The first teat didn't show anything in the pregnant window at the beginning but a thin blue line appeared an hour later. I tried another one right away, same thing happened in around an hour but the line was weaker.
Are these likely the evaporation lines and false positive?

Yes, anything that doesn't appear within the testing timeframe is invalid and almost certainly an evap.

It is likely an evaporation line, that’s why the instructions say not to read the test after the time instructed to read the results.

Retest again in a couple of days using FMU and read the test in the time it says. Good luck!

Thanks for the advice! Shall I stick with Clearblue or is there a better brand for early detection?

I would stick to clear blue personally. I know lots of people use first response but they often give a pale indent line which people can mistake for a positive too!
