Has anyone who tests regularly not get a BFP until after af was late?

I'm on cycle day 25 of a 26 day cycle being 12 days past ovulation and I haven't had a BFP but my temperature is still really high and I haven't had many PMS symptoms other than a headache today which was cured with caffeine.
What gives? Should I just give up testing and wait it out?
