1. What is the Menstrual Process?

Menstruation is a natural change in a woman's body that usually occurs between the ages of 11 and 16, although it can happen earlier or later depending on genetic factors, living environment, and diet. This process occurs when the ovaries develop and produce the hormone estrogen, which stimulates the thickening of the uterine lining. If fertilization does not occur, this lining sheds and is expelled from the body through the vagina as blood and tissue—this is menstruation.

2. Why Do Girls Have Their Periods?

Menstruation is a sign that a girl's body is developing physiologically and has the potential for reproduction. This is because of hormonal changes in the body:

• Estrogen: This hormone is responsible for stimulating the growth of the ovaries and the uterine lining. As estrogen levels rise, the body prepares for fertilization.
• Progesterone: If the egg is not fertilized, progesterone levels drop, causing the uterine lining to shed, which results in menstruation.

3. Why Do Girls Have Menstrual Cycles?

This process is part of the reproductive cycle, helping a girl’s body prepare for pregnancy. Every month, a girl's body undergoes a complex cycle to prepare for fertilization, and if pregnancy does not occur, the body eliminates the uterine lining through menstruation.

4. Menstrual Cycle Duration:

The menstrual cycle typically lasts between 21 to 35 days, with each period lasting 3 to 7 days. However, the length and frequency can vary depending on each person's body. Usually, after starting menstruation, girls will continue this cycle until menopause (around the age of 50).

5. Signs of an Upcoming Period:

Before menstruation, girls may experience symptoms such as lower abdominal pain, fatigue, mood changes, or skin changes. These are common signs and may vary from cycle to cycle.

6. Conclusion:

Menstruation is a natural and vital process for a girl's physiological development. It is a sign that the body is ready for reproduction and reflects the hormonal changes occurring within. Understanding this process helps girls and parents better prepare for the onset of puberty.
