My cycles have been always on point, same day at the exact time of day it will begin. This time it started a week early and a few days off. I have recently been under more stress, and my diet has been off as well. (Getting married) I am having dark brown spotting with an odor and it has be going on for over a week. I have recently began taking a probiotic in the last month, just a little extra info. Hoping you have some suggestions
