Faint positive then negative 2 days later? Please help!

Al
I took a test 2 days ago at 12dpo using a Superdrug test and I had a faint pink line within 4 minutes, posted it here and others saw it too, took the same test this morning at 14dpo and it's stark white, no hint 🙁 I've attached the photo from 12dpo. Could the negative be wrong, can anyone relate?
