Ugh I hate blue dye test

So I started taking blue dye (yeah I know lol) test at 7 dpo.

7 dpo - negative

8 dpo - negative

9 dpo - faint positive... Color and all

My husband, who is quick to tell me I have line eyes, said he saw it... So we go and get a first response test.... And of course it's negative 😑 I'm so close to crying 😢 i just want my rainbow...
