Is a faint line valid after 13 minutes?

Ariel

I think I see a line - let me know if you see it too! But I didn’t pay attention to it after minute 3, assuming it was negative. I didn’t look closely until minute 13 (instructions say to disregard results after 10 minutes) and thought I saw something. If there’s a line there, is it valid? I think I’m 2 days late. First photo is at 13 minutes, second photo is an hour later.
