Shadow line turn into bfp?

Jess

Had a shadow of a line today. Only 7 dpo, but decided to test after some things that happened yesterday.

Right away the line was pink. Then when I went to take a pic, it faded away!! Now that it’s completely dry, it’s just a very very hardly there shadow 😢

Tried to take pic & cant even see it in the pic.

Has anyone had this happen & end up getting their bfp later on??
