What is menstruation?
Menstruation is the monthly process in which a girl or woman's body sheds the built up uterine lining because fertilization has not occurred.
During this process, blood, along with the thickened lining and an unfertilized egg, is released from the uterus and leaves the body.
The menstrual cycle , which lasts an average of 28 days, marks the end of one cycle and the beginning of a new one. This process can be accompanied by cramps, mood swings, and other symptoms such as fatigue, but it is a normal and healthy sign that the reproductive system is functioning properly.
Of course, it doesn't mean that you will suffer from everything or that you will realize that you suffer from it. It could be that your environment, for example your mother, does notice that you have more mood swings and that your hormones are starting to play up.
This process usually begins during puberty, often around the ages of 11 to 14, but it can also begin earlier or later.
Menstrual periods can also vary in length, usually between 3 and 7 days, and the amount of blood loss can vary from person to person.
