a friend's test

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​wasnt sure which group to post this to, THIS IS NOT MY TEST. its my friends, and i have seen on here so much about how unreliable the blue dye tests are. so i wanted to see what y'all thought. i noticed how the line isn't full, like there's some color missing in the middle. she's a few days past her expected period, but said she spotted for a few days last week but it was darker blood, not light pink. and she never had light pink spotting like implantation bleeding. i know not everyone gets it because i am 6 months and never had it with either pregnancy. just looking for other opinions. I already told her to double check with a pink dye one. thanks!
