I spotted three days & the next day I got my period. It only last two days. The first day it was really heavy, the next day I was just spotting. It stopped all day, I didnt have any of the brownish stuff. I woke up the next day at 2 am and felt wet. I thought I peed myself but it was blood I put a tampon on and I woke up the in the afternoon and I had no more blood. What could this be?
