The first day of my last period was August 10, and bleeding lasted until August 15. But since yesterday, Aug 29, I've been having light spotting. It isn't exactly pure blood and is pink, and seems mixed in with some vaginal discharge. I haven't had any sex. But I've been through a lot of stress this month because of an important exam. The bleeding actually only started the night after I took the exam.

I also have a migraine now, much like what I have when I menstruate. Although, I didnt experience any PMS symptoms (which I usually have before I menstruate) prior to the bleeding. 

This is very unusual to me. I have no idea if this is my already period that has just come early (by around 10 days), or something else entirely.
