hi i have this strange questiong, it's been 2 weeks after my d and c the darker pregnancy test would be the pink one, correct? if it was after my d and c shouldn't it be lighter then the others?

note that some are older, pink one was take 24 hours ago, yes I understand they can change and are not valid, but I'm not asking if I'm pregnant because I did have a miscarriage, they have stayed the same brightness of color.
