Faint line or evap?

K

Hey all! I am not currently TTC and have the IUD but for context my first born was conceived on the pill. I got random spouts of throwing up last week and took a test but it was invalid, tested again today and I swear I see a faint line ? Am I crazy or is it an evap line ? Either way second opinions are appreciated as i try and figure out if I need to see the GP 😅
