First Period Guide: Everything Every Girl Should Know
Getting your first period is an important milestone in every girl’s life. It marks the beginning of the menstrual cycle and is a natural part of growing up. While it can feel exciting, confusing, or even a little scary, understanding what to expect can make the experience much easier.
This First Period Guide explains when periods usually begin, the signs to look for, menstrual hygiene tips, and when medical advice may be needed.
What Is a First Period?
A girl’s first menstrual period is called menarche. It usually happens during puberty when the body becomes capable of reproduction.
Most girls get their first period between the ages of 10 and 15 years, although the exact timing varies from person to person.

Signs Your First Period May Be Approaching
Many girls notice changes in their bodies before their first period, such as:
- Breast development
- Growth of underarm and pubic hair
- White vaginal discharge
- Rapid growth in height
- Mild abdominal cramps
- Mood changes
- Acne
These changes are a normal part of puberty.
What Does a First Period Look Like?
Your first period may be:
- Light pink, brown, or bright red
- Very light spotting or a slightly heavier flow
- Last between 2 and 7 days
It is normal for the first few periods to be irregular as your body adjusts.
Common Symptoms During Your First Period
You may experience:
- Mild cramps
- Lower back pain
- Bloating

Not every girl experiences all of these symptoms.

Use the Right Menstrual Product
Girls can choose from:
