What Is Menstruation?

Menstruation is the monthly bleeding associated with a woman's menstrual cycle.

The menstrual cycle is the series of hormonal changes that a woman's body goes through in preparation for pregnancy.

Each month, the lining of the uterus (or womb) thickens. Your body sheds this lining, along with blood, if no fertilized egg attaches to the wall of the uterus.

The blood and tissue pass out of the body through the vagina.

The menstrual period, or menstruation, typically lasts three to five days for most women.

Every woman's menstrual cycle is slightly different. A normal menstrual cycle length can be anywhere from 21 to 35 days. The average length of a menstrual cycle is 28 days.

Period Calculators

Many women track their menstrual cycles. If you're trying to become pregnant, keeping a record of your period can help you figure out when you're ovulating and whether your period is late.

Tracking periods can also help you spot any irregularities or changes to your menstrual cycle.

The U.S. National Institutes of Health (NIH) recommends marking each day of your period with an "X" on a calendar. Note any pain or changes in flow.

There are a number of websites and apps that offer free period trackers or period calculators.

Be aware, though, that many period-tracking apps have been found to be inaccurate, according to a June 2019 review in the journalObstetrics and Gynecology.

Menstrual Cramps (Dysmenorrhea)

Dysmenorrhea, or menstrual cramping, is pain associated with menstruation.

Menstrual cramps are common. More than half of all women who menstruate report some pain for one to two days each month, according to the American College of Obstetricians and Gynecologists.

Hormones called prostaglandins can cause normal menstrual cramping. Prostaglandins are produced by the lining of the uterus.

Cramps usually occur right before menstruation starts and may last for a day or two. Pain typically decreases throughout the period as you shed the uterine lining.

See your doctor if pain gets worse as menstruation continues, doesn't go away after the end of the period, or is so severe that it affects your daily living. These may be signs of a more serious medical problem.

Irregular Periods

Certain menstrual cycle disorders can cause a woman's period to be irregular, absent, or infrequent:

AmenorrheaThis term refers to the absence of periods for three to six months in a woman who has previously had periods or when menstrual periods haven't started by age 15.

Oligomenorrhea:This is a medical term for infrequent periods. Women with oligomenorrhea have fewer than six to eight periods in a year.

See your doctor if you miss more than three menstrual periods in a row, or three menstrual periods over the course of a year.

A number of conditions can cause irregular periods, including problems with the ovaries, uterus, cervix, vagina, or hormone-releasing centers in the brain.

Heavy Periods

Menorrhagia is the medical term for menstrual bleeding that lasts longer than normal or is very heavy.

Heavy periods can be a sign of other health problems. They also can lead to anemia (low red blood cell count, or lack of hemoglobin in the blood) from the increase in bleeding that occurs.
