Is this an evaporation or positive BFP?

It came up after the time, I had to unexpectedly pop out and checked it after an hour!!
it’s definitely pink in real life!!

If it didn't come up in the time you have to discount it. That said, it does look like a decent positive so I'd retest asap.

After the time is not valid

Annoyingly I don’t even know if it was in the time - although I see now my original post doesn’t make that clear!!
I had to dash out after 1 or 2 mins and then wasn’t back for an hour ish.
so I saw it after the time but who knows when it came up!
Retest in the morning!!

Good luck! Fingers crossed for you! Tbh I'm leaning towards positive but do update!
