I'm always have had a very prediticble period.. every month like clockwork since as far back as I can remember.

Then today, I'm minding my own business, not peeing on sticks a week early like I normally would. Then BAM, major cramps. I run to the bathroom to find blood..more blood than there should be. Only to check the calender and I'm 4 days early. I may have been late before but never ever this early.

I didn't even have those weird could-this-be-pregnancy-of-course-not-it's-aunt-flow-time-again type symptoms as a warning this time.

What the heck is happening?
