Faint line again? 🤔

Aubs
Super hard to see in the pic, but it's there and pink in person. Shined a light behind too to see. Only issue? After 5 minute time limit. Thing is, I've tested on 10 different tests over the last month, (ordered a huge pack from Amazon), and never had any type of second line before now... Anyone have experience with these tests? Thanks?Â
