A woman's period is important for regulating hormones and plays a vital role in pregnancy. A period occurs when an egg is unfertilized. An unfertilized egg triggers the uterus to shed thickened lining that would have protected a fertilized egg during growth. The Office on Women's Health states that the average period lasts three to five days. Some women have week-long periods.
