Feeling like giving up

I'm 5 day late and still no af??? I keep buying all of these tests and it's like nope not today when am I going to get that bfp or af?? I really want that bfp but now I'm like something needs to show even if it is af at least I won't have to keep my hopes up every day when I take that test. Has anyone ever been pregnant and a hpt just wasn't able to detect it? How long did you wait before you got a bfp?? I've never ever have been late before... Any advise would be helpful
