## What is the Menstrual Cycle?
The **menstrual cycle** is the time from the first day of your period to the day before your next period starts. Most women have a cycle that lasts between **25 to 35 days**, with 28 days being the average.
This is the time when bleeding happens. It is often called a “period.” It usually lasts between **3 to 7 days**. This happens because the uterus lining is being shed from the body through the vagina.
### Common symptoms during your period: - Cramps - Mood swings - Headaches - Feeling tired
This phase starts the menstrual cycle. Day 1 of your period is **Day 1 of your cycle**.
---
## 2. Follicular Phase
This phase starts on the **first day of your period** and lasts until **ovulation**.
During this time: - Your brain sends a hormone (FSH) to your ovaries. - This helps eggs grow in small sacs called **follicles**. - One egg becomes mature and ready to be released.
Your body is getting ready for a possible pregnancy.
---
## 3. Ovulation
**Ovulation** is when a mature egg is released from your ovary. This usually happens around the **middle of your cycle**, around **Day 14** in a 28-day cycle.
### Important Facts About Ovulation: - The egg lives for **12 to 24 hours**. - This is the **most fertile time** in your cycle. - Sperm can live up to **5 days** in your body. - So, the fertile window is usually **6 days long** – 5 days before ovulation and 1 day after.
You may notice some signs of ovulation, like: - Clear, stretchy vaginal discharge (like egg white) - Mild cramps on one side - A small rise in body temperature - Increased desire for intimacy
---
## 4. Luteal Phase
After ovulation, your body prepares for pregnancy.
- The empty follicle turns into a structure called the **corpus luteum**. - It makes the hormone **progesterone**. - Progesterone thickens the uterus lining to support a baby.
If the egg is not fertilized: - The corpus luteum breaks down. - Hormone levels drop. - The uterus lining sheds, and your next period begins.
---
## What is a Period Calendar?
A **Period Calendar** is a tool to help you **track your menstrual cycle**. It can be a paper calendar, a phone app, or a journal where you note down:
- Start and end date of your period - Days when you feel pain, cramps, or mood changes - When you think you ovulated - Your fertile days
This helps you: - Know when your next period is due - Identify changes in your cycle - Plan or avoid pregnancy
Using a period calendar has many benefits, such as:
### 1. Better understanding of your body You will learn how long your cycle is and how your body feels during different times of the month.
### 2. Helpful for pregnancy planning If you are trying to get pregnant, knowing your **fertile window** helps you try at the right time.
### 3. Helpful for avoiding pregnancy If you do not want to get pregnant, you can avoid sex during your **fertile days**.
### 4. Track health problems If your period is irregular, too heavy, or causes too much pain, you can show your calendar to a doctor.

## What Are Fertile Days?
**Fertile days** are the days when a woman is most likely to get pregnant. These are the **days around ovulation**, when the egg is available and sperm can meet it.
### In a 28-day cycle, fertile days are usually from Day 10 to Day 17: - Sperm can survive in the body for up to **5 days**. - The egg survives for about **1 day** after ovulation. - That’s why you can get pregnant even if you had sex a few days before ovulation.

### 4. Ovulation kits You can buy ovulation prediction kits (OPKs) at the pharmacy. These test your urine for hormones.

## What is the Ovulation Day?
**Ovulation day** is the **single day when the egg is released** from the ovary.
In most women, ovulation happens **about 14 days before the next period**. If your cycle is 28 days long, ovulation usually happens on **Day 14**.
This is the **best day** to try to get pregnant.

## Period Irregularities to Watch For
While every woman’s cycle is a little different, you should talk to a doctor if you notice:

**But remember**: This method is not 100% safe unless you track your cycle very carefully. It’s better to combine this with other birth control methods if you want more protection.
