It’s possibly a faint line but I don’t see enough there to say it’s positive. It looks more like an evap/indent. By 5 days late it would be much darker, in my experience unless you ovulated late.
I agree with @MysticKitten. If you think you could possibly have ovulated late, test again in a few days.
I am so unsure. I had light bleeding for 3 days, like implantation and again I just had my first period since giving birth
