Faint positive or evap lines?

[NixieJH]

Here’s a timeline of what’s happened in the last week:
first test - faint positive at 4DPO (I use Flo to estimate. It’s usually accurate)
negative at 5DPO
Faint positive at 6DPO
Negative every day since until today
2 faint positives (I think??) at 9DPO. The photo is of the 9DPO today. Later I will add the photos of my first faint positives.

What’s happening?? Am I having a very early chemical pregnancy?? I know I’m gonna be told to wait a few more days but I wanna know if anyone has experienced this before and what the outcome was?

4DPO and 6DPO

Update on 10DPO:
Cramping has got way more noticeable today, similar to start of PMS cramps. Period is due in 3 days.

Latest update.
Period started today. Every other test and brand I used was negative. Found other people online complaining about false positives from Asda tests.
I will take another test after my period just to be absolutely sure.
I did think it was strange that a positive result was showing at 4DPO.
