Not sure how to read? Faint line?

Day 30 of cycle (cycle is normally about 31 days but varies 29-34!), 13DPO.

Brand of test is an unknown French brand that claims to be sensitive up to 8 days after conception.

In certain lights I feel like I can see a vvvvfl slightly to the left of the test box. It’s hard to see properly because of the plastic casing. Probably just wishful thinking and likely a shadow/ evap?

Thanks for your thoughts.
