Like clockwork, AF...just like clockwork.

Does anyone else feel like the second they're maybe pregnant and they go to take a hpt, stupid AF shows up. I mean seriously, I held out for a few days, anxiously waiting to take a test and the minute after I do, and after light spotting for two days which is highly unusual, of course AF comes knocking. And hpt hasn't even given answer, screen just went blank. Sorry for the negativity, needed to vent ? Rant over.
