Is this an evaporation line?

Am I making up seeing a line on the red test?
I was so excited, so I did two clear blue tests, thinking they’d say ‘pregant’ - but nothing.
is the red test an evaporation line? I’m relatively new to tests and trying to get a positive test- myself and my
partner have been trying since September. Any advice really greatly appreciated 🥲

Looks positive to me.
What brand is the pink dye test? Is it possible it has a lower sensitivity? Also wete they all taken with the same urine sample?

Different wee samples. Brand for red test was Wondfo off Amazon and brand for blue tests were clear blue. I’m not sure re the lower sensitivity - might sound stupid but how do I find out?

I can see a faint line on the Wondfo!!! I used the Wondfo and they were more sensitive than the others. I can't remember what the sensitivity is but it does say it on Amazon (if you ordered them from there)..

When is your AF due? I got some solid BFPs 1-2 days before AF.. I am now 18DPO and CB is showing the 2-3 weeks pregnant :)

not at all, I only joined Mumsnet a few months ago and am still struggling with the lingo lol.. I think it stands for Aunt Flo which is basically our 'period'...

So you're 2 days before AF/your period. Definitely worth testing again tomorrow. Maybe save the wee and try a couple of tests just in case.

I had similar, the best test I found was first response - available on Amazon.
They are super sensitive.
My first response was positive but clear blue digital was neg?!?
I am now 17 days past my ovulation and very much pregnant!
So you want clear blue ultra early or frer. The clear blue you have are not the early ones, and tbh i found them not as good in early testing.
Wondfo are good, but most of the time you are second guessing it!
I found premom really good for progression.

These were my tests, at around 9 days past ovulation.
Clear blue early digital also said not pregnant the next day but other tests were saying otherwise!

The sensitivy will be written on the pamphlet than xame with the tests. Or you could probably Google the sensitivity of the brands.

Also, only test with FMU. If these were all different wee samples throughout the day they aren't comparable as some wee will have a longer hold and less dilution (first morning urine) than middle of the day when you've had drinks and been for a few wee's
