I got 2 faint positives on blue dye in different time frames hours apart & i just took a pink dye and it was negative.. Can it just be to early to pick up on the pink dye?

And i know it can be a chemical i just hope that is the last option because ive already had 3 in 2020..

The first blue dye i took, popped up within the time frame.

The second one i took HOURS after, its so faint its an eye squinter but u can see it more in person

( The dye run wasnt there when the line first popped up, and it went away after like 3 seconds and the lines still there )

And this is my pink dye i just took and its negative
