CD 33 and still no AF. Negative test. Am I out?

Lindsay
So the last 2 months I've had a 28 day cycle. I tested a day before AF was due and I got BFN. Then AF still didn't show! I'm now on CD 33 and still no AF. I tested yesterday and got another BFN. Is it safe to say I'm out? I just want to get AF so I can try again lol!
