Test again??

Alaina • Ttc my third and my husbands second. Wishing the best if luck to everyone out there!
Tiday is cycle day 33, AF was due the 23. So far no AF, which is good. I took a test on the 20 when glow suggested, bfn, took a test Saturday the 24 when AF was a few days late, bfn, which is bad. So do I just keep waiting around? Or do I test again? I'm so confused !
