BFN - AF late

Lucy
I'm super super clockwork. In the spring I ended up not being on birth control for 2 months and my periods were still a very reliable 28 day cycle. I was due yesterday and have no sign that AF is coming. I tested Thursday, Saturday and this morning and they were all clearly negative. 
I'm just frustrated. I feel like my body is tormenting me. I'd made peace with not getting a BFP this month, and now I'm confused.
