Why do I keep getting these shadow lines? :( they are driving me nuts

I've tried both. They look pretty similar.

Blue dye tests suck for early testing. Try red dye

give it some more time , but i deffntly see that very faint line i tweaked it with my app & i see it. ive had that issue at first but when i gave it time i got what i wanted.

I just don't get ittttt. Are they always there?

I have done a million test and always see this line but with the pink ones I never can tell :(

seeing a very faint line going down , dont give up ❤️
