My period was due, 2/14/13. Normally, my breastsget sore about a week post menstration however on this occasion it began faintly on the day that I was to begin my period. Finally, on 2/20/13 I noticed a small amount of pinkish mucous in my underwear and when I proceeded to wipe myself a strand of brownish blood appeared on the tissue. For the past two days I have been able to see some pinkish blood, but only when wiping myself.
