Faint line or evap line

Hi everyone I am back on here following a what I believe is a positive test. I am still unsure if it’s positive or an evap line wondered if I could get more eyes on it to distinguish if it’s a positive. This will be our rainbow baby following a miscarriage last April 😔 so super excited but at the same time so scared and overthinking everything!! Apologies for the terrible photo it’s difficult to get a clear image 😩 I believe I am 4w3d (due 18th December) so still very very early!
