Help! What does this mean?

[Catmum92]

I took a test this morning - 8 or 9 dpo.
theres nothing to see in the original pictures except I noticed a light patch in the spot where the second line would appear.
The inverted image shows it better. Does this mean anything? Or just an evaporation/ indent?

Almost certainly an indent. There is no colour in the line at all.

That's just where the dye would take but no colour is negative. I've had loads of weird issues with E@H lately, really bad evaps etc. I think the quality has deteriorated since I used them when TTC my first.

Thank you both
