Line eyes and evap/faint positive

[Saffia]

Hi, first time posting here so unsure if this is correct.

I have been ttc for 3 months.
On Sunday 13th I had brown spotting sort of which then disappeared and now nothing.
Have been getting normal AF cramps but no sign of yet.
I’m on CD38 currently.
I have done multiple tests with different answers.
A lot of them have faint positives but then some are negative and an Asda digital was not pregnant.

I know not to take tests apart but these lines were there within the time limit and could see them, only took them out to get a closer look as I was shocked. I also know that Tesco do bad evap lines but these are very blue in person and they glow when inverted. I have had other lines like this on different brands too.

Inverted

This was my first response taken same time as the Tesco ones

I can see very faint lines but they all look like evap lines to me. How long is your cycle normally?

Thank you for replying. I’m unsure to be honest. This is my 3rd cycle since giving birth in September 2021 and my previous two have been 38 days and 40 days.

It’s currently CD38.

I did think they were evap, only thing that makes me think otherwise is the brown sort of spotting I had on Sunday.
