Not Sure What To Think

*Cross posting because I'm not sure where this one goes*

Hey ladies! So, AF is about a week late, and I decided to order some tests. They came today and I just tested. I got a negative twice (I'll include a pic of the tests, but there's no question that they're negative). So, I think I'll test again in the morning because I am SUPER regular usually, and for me to be a week late is very odd.

My question is, shouldn't I have gotten a positive result any time of the day at this point, or are the hormones still so low that they might only be detected in the morning?
