What is the meaning of menstruation in a girl?

Menstruation is the process of shedding the lining of the uterus (womb). It occurs when a fertilized egg does not implant in the uterus. The lining of the uterus, which is made up of blood vessels and tissue, breaks down and is shed through the vagina.

Menstruation is a normal part of a woman's reproductive cycle. It usually begins between the ages of 12 and 15, but can start earlier or later. The average menstrual cycle lasts for 28 days, but can vary from 21 to 35 days.

During menstruation, a woman may experience a variety of symptoms, including:

* Cramping

* Bloating

* Mood swings

* Fatigue

* Headaches

* Acne

* Breast tenderness

These symptoms are usually mild and go away within a few days. However, some women experience more severe symptoms that interfere with their daily activities. This condition is called dysmenorrhea.

Menstruation is a natural process that prepares a woman's body for pregnancy. It is also a sign of good health. If you have any concerns about your menstruation, talk to your doctor.
