help! faint positive ?

10dpo, Obvious nausea, insomnia and no longer like the taste of coffee (my favourite) since 3dpo, but still keep getting negative tests! This one came back with a pink spot at the top of the test line - Anyone else have this ? I feel like an absolute nutcase, I just know my body feels different but the damn tests keep being negative!! 😫 period due in 2 days ☹️
