I dont get it?

Can someone explain to me....on OTK boxes it says DO NOT READ AFTER 5 MINS. And yet all these women post photos of like a WEEKS worth of tests and say "I dont see a difference?" Excuse me if in wrong but yeah you ain't gonna see shit cuz it specifically says dont read after 5 mins. Shit dries out, the test becomes invalid. And you guys look at them still after 3 days? AND some of you are grabbing pregnancy tests out of the garbage DAYS LATER saying I see a positive even though it was negative. Like???🤦‍♀️ you dont read those tests after 5 mins, not even days after! Wtf am I missing?
