Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle. Every month, your body prepares for pregnancy. If no pregnancy occurs, the uterus, or womb, sheds its lining. The menstrual blood is partly blood and partly tissue from inside the uterus.
But, it is also common and very normal for your own menstruation to change from month to month. A normal range for menstruation is every 21 to 35 days. Depending on the month, your period may come a few days early/late or your menstrual flow may be heavy/light.
