Helppppp AF late no real BFP

Today is CD 34. Af was due yesterday. I’ve had many unsure tests. Some really faint lines that I couldn’t tell if they were indents or not. Some disappearing lines etc. BUT the last time DH and I had sex was 21 days ago 🤔 af is NEVER late. I usually have 32 day cycles and af usually comes right on time or a day early. But it’s been over a year since I’ve gone to cd 34 with no AF. I have no tests left and will go get some more today but I’m just baffled. If I’m pregnant wouldn’t I have a blazing positive by now?? I’ll post some of my tests in the comments. Any input? Thanks!
