Positives at 11am any other time negative

[PM05]

We have been actively trying for nearly 2 years was about to start fertility testing when i was 2 days late so I tested positive last thursday at 11am (18th of Sept),then negative in evening then positive again at 11 on friday (19th) had some spotting sat-mon and retested at 11 on 24th (wednesday) and positive
have been for bloods and waiting but tested at 1.30 today with digital (all others been non digital) and its negative

am i overthinking or should i be worried?
photos are top of double is 18th then 19th single one is 24th

I'm really sorry, these all look like evaporation lines rather than positives. They are too thin and not a consistent colour. I don't think these are positives at all sad 😢

The three were there when check after 3 minutes

Unfortunately I agree OP. These are not positive tests. A positive line is thick, and the dye is even.
I'm really sorry, but if you are this late I'd assume you are not pregnant. Unless you don't track ovulation, in which case you may not in fact be 'late' yet in terms of dpo.
I'd avoid these tests in future as they are notorious for doing this.

I am 21 dpo
i had bloods yesterday so hopefully have an answer soon either way to move on
