Quoting ☮ Phuket:" my pee was kinda diluted from the coffee ive been drinking but that shouldnt matter right? i may or ... [snip!] ... matter right? i may or may not hold my pee for as long as absolutely possible and test again later on since i have 3 tests"
Personally, I'd still be skeptical if it was me. Just saying.
I'd definitely try to hold it all night and test again with FMU just to be SURE, if not hold it for like four hours (not drink ANYTHING) and test this afternoon.
That's just me... That's insane to me. IDK... I've seen false cheapies at least four times now, like serious lines. That's just crazy.
