The Menstrual Cycle

Have you ever wondered what your body is doing between one period and the next? Your body is actually working all month long as part of something called the menstrual cycle.

Understanding your menstrual cycle can help you know what to expect, prepare for your next period, and better understand the amazing changes happening inside your body.

What Is a Menstrual Cycle?

Your menstrual cycle is the monthly process your body goes through to prepare for a possible pregnancy in the future.

Each cycle begins on the first day of your period and ends the day before your next period starts.

Even if you're not thinking about having children now, your body is naturally learning how to do this as you grow.

How Long Is a Menstrual Cycle?

Most menstrual cycles last between 21 and 35 days, although every girl is different.

When you first start your period, your cycles may not come at the same time every month. It can take a few years for your cycle to become more regular, and that's completely normal.

How Long Does a Period Last?

A typical period lasts 3 to 7 days.

Some girls have lighter periods, while others may have heavier flow during the first few days. Every body is unique, so your period may not look exactly like someone else's.

What Happens During the Menstrual Cycle?

Your body goes through four main stages during each cycle.

🩸 Days 1–5: Your Period

Your cycle begins on the first day of bleeding.

During this time, your body sheds the lining of the uterus because it is no longer needed. This lining leaves your body through the vagina as your period.

You may experience:

  • Cramps

  • Tiredness

  • Mood changes

  • A heavier flow during the first few days

🌱 Days 6–13: Building a New Lining

After your period ends, your body gets ready for the next cycle.

Hormones tell your uterus to build a fresh, soft lining filled with nutrients. At the same time, an egg begins to mature inside one of your ovaries.

Many girls notice they have more energy during this part of their cycle.

🥚 Around Day 14: Ovulation

About halfway through the cycle, one of your ovaries releases a mature egg. This is called ovulation.

The egg travels into the fallopian tube, where it could be fertilized by sperm during adulthood if a pregnancy were to occur.

If the egg is not fertilized, it simply breaks down naturally.

🌼 Days 15–28: Preparing for the Next Cycle

After ovulation, your body continues preparing for a possible pregnancy by keeping the lining of the uterus thick and healthy.

If pregnancy doesn't happen, hormone levels begin to drop. This tells the uterus it no longer needs the lining, and a new period begins.

Then the cycle starts all over again.

What Do Hormones Do?

Hormones are the body's chemical messengers. They work together throughout your menstrual cycle to tell your body what to do.

They help:

  • Start your period.

  • Build the lining of your uterus.

  • Release an egg during ovulation.

  • Prepare your body for the next cycle.

Hormones can also affect your emotions, energy levels, appetite, and skin. You may notice that you feel different at different times of the month, and that's completely normal.

An Easy Timeline

Here's a simple way to remember the four stages of your menstrual cycle:

Days What's Happening
🩸 Days 1–5 Your period begins, and the lining of the uterus leaves your body.
🌱 Days 6–13 Your uterus builds a new lining while an egg matures.
🥚 Around Day 14 Ovulation happens, and an egg is released from an ovary.
🌼 Days 15–28 Your body prepares for the next cycle. If pregnancy doesn't happen, your next period begins.

Why Is It Helpful to Know Your Cycle?

Learning about your menstrual cycle can help you:

  • Know when to expect your next period.

  • Feel more prepared at school or while you're out.

  • Understand why your energy or emotions may change throughout the month.

  • Take good care of your body with confidence.

As you get older, you may even choose to track your cycle on a calendar or in an app to help you notice patterns.

Growing with Confidence

Your menstrual cycle is a natural and healthy part of growing up. While it may seem complicated at first, it's simply your body's way of preparing for the future each month.

Remember, every girl's cycle is different. Some cycles are shorter, some are longer, and they may be irregular when you first start your period. That's all part of growing.

The more you understand your body, the more confident you'll feel. At Anza, we're here to help you learn, ask questions, and celebrate every step of your journey with confidence. 💜
