How dark does a line need to be for you before you trust it/consider it a BFP?
I've got a squinter on an easy@home test this morning, they're meant to be 10mlu tests so fairly early. 9dpo today.
It's still only faint, so I daren't trust it yet in case of it being a chemical. But it's very definitely there. I don't think I'll trust it until it's dark enough for my partner to see it, so pretty much flashing in neon!
It made me wonder at which stage others trust that their second line is a genuine bfp? Is there a standard that I've missed? I know some US groups wait for a dye stealer but I've never had one in previous pregnancies so I'd have given birth before considering myself genuinely pregnant 
Please excuse my bedside table, it was cleaned after I took these - it seems to attract dust and a child's added some lovely sticky finger prints to it!
