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.
Dr Laura Cassidy, an obstetrician and gynaecologist, explains whatâs normal and whatâs not for your monthly period. Periods last around three to seven days. The average menstrual cycle lasts 28 days, although itâs normal to have a cycle that's shorter or longer than this.
