Why Do Girls Get Periods? The Menstrual Cycle Explained for Curious Kids

Every girl’s body is amazing and goes through different changes as she grows up. One of these big changes is called the menstrual cycle. You might have heard people talking about a "period." This happens during a girl’s menstrual cycle. Let’s learn what the menstrual cycle is, how it works, and what it means for growing girls!

What is the Menstrual Cycle?

The menstrual cycle is a process that happens inside a girl’s body to help it grow and stay healthy. It usually begins when girls are between 9 and 16 years old. Everyone is different, so it’s okay if it starts a little earlier or later. This cycle happens every month, and it involves changes in the body that prepare for something called a period.

What is a Period?

A period is when a girl’s body releases a small amount of blood and tissue. This comes from the inside of her uterus (also called the womb). The blood leaves her body through a part called the vagina. This is completely normal and is a sign that a girl is growing into a young woman.

Periods usually last about 3 to 7 days. It happens about once a month, and this monthly pattern is called the "menstrual cycle." The time between periods is usually around 28 days, but it can be shorter or longer for some girls.

Why Do Girls Have a Menstrual Cycle?

The menstrual cycle is the body’s way of getting ready for future changes. Each month, the body builds up a special lining inside the uterus. This lining is soft and has nutrients. When the body doesn’t need this lining, it comes out as a period. Then, the cycle starts all over again!

Phases of the Menstrual Cycle

The menstrual cycle has different phases or steps. Here’s a simple breakdown:

1. Menstrual Phase: This is when the period happens. The body is shedding the lining of the uterus.

2. Follicular Phase: After the period ends, the body starts building a new lining in the uterus. It also prepares an egg inside the ovaries.

3. Ovulation: Around the middle of the cycle, the body releases an egg. This is called ovulation. It usually happens about 14 days before the next period.

4. Luteal Phase: If the body doesn’t need the new lining, it prepares to shed it. Then, the cycle starts over again with the next period.

How to Know When Your Period is Coming

Every girl’s body gives some clues before a period starts. These clues are called PMS (which stands for Premenstrual Syndrome). Some common signs are:

• Feeling more tired than usual.

• Getting small cramps (a type of tummy ache).

• Feeling a little grumpy or sad.

• Swollen or sore breasts.

• Pimples on the face.

These signs are normal, and they usually go away when the period begins.

How to Take Care of Yourself During Your Period

Periods are a normal part of life! Here are some simple ways to stay comfortable:

• Use Pads: Pads stick to your underwear and catch the blood. Change them every few hours.

• Stay Clean: Take a shower every day and wash your body well.

• Rest: If you feel tired, it’s okay to take it easy.

• Drink Water: Staying hydrated helps you feel better.

Things to Remember
