Pregnancy test

[Applegarth23]

Hi
So my ovulation date was 29th Jan and we Dtd on 30th and a few days after that (ttc). I started to experience light pinkish brownish spotting which started on the 7th February. It’s now been three days since this and sometimes when I wipe there’s pale pink spotting. My cycle is 28 days I’m never late or early. I’m due to start on Friday but have done a few tests (Asda and clear blue)that have show very very faint positives. I’ve also tried a few cheap £1 tests from home bargains which came back negative.
I’m experiencing a backache, headache and fatigue which I’ve never experienced before my af.
Also the positive test albeit very faint we’re not my fmu they were from the afternoon.
The latest clear blue early detection was also from this afternoon which I’m very confused as I’m not sure whether to read it as a faint positive or evaporation line.
Could someone please share their thoughts on this I would really appreciate it!
Thank you in advance:)

Sorry I’m not sure why the picture has not been posted

If you are new you can't post photos straight away. Sounds positive though !

Bubbles1st thank you that’s probably why!

As my account was new I was unable to attach pics. I’m unsure whether these are extremely faint positives or evaporation line.

Have you taken a test since then?
Since it’s been 2 more days a test should show slightly clearer by now if it’s a true positive.

I do see a shadow on the cheap test. The clearblue looks smudged so I’m not sure if trust it.
