Period ...?

I had the lightest shortest period I've ever experienced in the 10 years of having of having periods!!!

I usually have a 5 day cycle,

The first 3 days its pretty heavy, by the 4th day it gets light and I spot on the 5th day.

Its always like that every time.

Well this time my period lasted 3 days and the first day its was lightish. The second day my pad for the WHOLE day was just a little pink and my third day I didn't even wear a pad and no blood was in my underwear just a little pink when I wipped and that's it.

Has this happened to anyone else?

May it be stress related?!
