What Is a Period?
Quick Answer
A period is when a small amount of blood leaves the body through the vagina over a few days each month. It is a normal and healthy part of growing up for people with female bodies, usually starting between ages 9 and 16. Periods happen because the body is preparing itself each month in case a baby might grow someday.

Ages 6-8 More Detail
A period is something that happens to people with female bodies as part of growing up. About once a month, a small amount of blood comes out of the body through the vagina. It might sound surprising, but it is completely normal and healthy.
Periods happen because of something really cool the body does. Each month, the body builds a soft, cushiony lining inside a body part called the uterus. If a baby is not going to grow there that month, the body lets go of that lining, and it comes out as a period.
Most girls start getting their period sometime between ages 9 and 16. A period usually lasts about 3 to 7 days, and then it stops until the next month. People use pads, tampons, or other supplies to catch the blood so it does not get on their clothes.
Having a period does not mean a person is sick or injured. The blood is not from a cut or a wound. It is just the body's way of refreshing itself and starting a new cycle. People can still do all their normal activities during their period.
Some people get cramps in their belly during their period, which can feel like a stomachache. Resting, using a warm heating pad, or gentle movement can help cramps feel better. If someone you know is on their period and seems a little uncomfortable, being kind and understanding is always a nice thing to do.
Ages 9-12 Full Explanation
A period, also called menstruation, is a normal part of growing up for people with female bodies. About once a month, the uterus sheds its inner lining, and this lining exits the body through the vagina as blood and tissue. A typical period lasts anywhere from 3 to 7 days.
Here is why it happens: each month, the body prepares the uterus for the possibility of a pregnancy by building up a thick, blood-rich lining. When pregnancy does not occur, the body does not need that lining anymore, so it breaks it down and releases it. Then the cycle starts all over again.
Most girls get their first period between ages 9 and 16, though 12 is a common age. The menstrual cycle — the time from the start of one period to the start of the next — is usually about 28 days, but it can range from 21 to 35 days. When periods first start, they are often irregular, meaning they might not come at the same time every month.
People use different products to manage their periods, including pads that stick to underwear, tampons that are worn inside the body, and menstrual cups. Choosing which product to use is a personal decision, and many people try different options before figuring out what works best for them.
It is common to experience some discomfort during a period, like cramps in the lower belly, headaches, or feeling more tired than usual. Gentle exercise, staying hydrated, eating nutritious food, and using a warm compress on your belly can all help. If cramps are really painful, talking to a doctor is a good idea because they can suggest ways to help.
Getting your period is nothing to be embarrassed about, even though it can feel that way at first. It helps to keep some supplies in your backpack or locker so you are prepared. And remember — about half the world's population gets periods, so you are definitely not alone.

Tips for Parents
A period can be a challenging topic to discuss with your child. Here are some practical tips to help guide the conversation:
DO: Follow your child's lead. Let them ask questions at their own pace rather than overwhelming them with information they haven't asked for yet. If they seem satisfied with a simple answer, that's okay — they'll come back with more questions when they're ready.
DO: Use honest, age-appropriate language. You don't need to share every detail, but avoid making up stories or deflecting. Kids can sense when you're being evasive, and honesty builds trust.
DO: Validate their feelings. Whatever emotion your child has in response to learning about a period, acknowledge it. Say things like 'It makes sense that you'd feel that way' or 'That's a really good question.'
DON'T: Don't dismiss their curiosity. Responses like 'You're too young for that' or 'Don't worry about it' can make children feel like their questions are wrong or shameful. If you're not ready to answer, say 'That's an important question. Let me think about the best way to explain it, and we'll talk about it tonight.'
DO: Create an ongoing dialogue. One conversation usually isn't enough. Let your child know that they can always come back to you with more questions about a period. This makes them more likely to come to you rather than seeking potentially unreliable sources.
Common Follow-Up Questions Kids Ask
After discussing a period, your child might also ask:
What age do you get your first period?
Most girls get their first period between the ages of 9 and 16, with 12 being a very common age. The timing depends on your body and your genetics. Getting it earlier or later than your friends is completely normal.
Does getting your period hurt?
Some people feel cramps in their lower belly, which can range from mild to uncomfortable. Not everyone gets cramps though. Things like a warm heating pad, gentle exercise, and staying hydrated can help. If cramps are very painful, a doctor can help.
How long does a period last?
A period usually lasts between 3 and 7 days. The flow is often heavier in the first couple of days and lighter toward the end. Everyone is a little different, and your period may vary from month to month, especially when you first start.
Can you still do normal activities during your period?
Absolutely! You can go to school, play sports, swim, hang out with friends, and do everything you normally do. Using the right period products means you can stay comfortable and active throughout your period.
What if I get my period at school?
If you get your period at school, you can go to the restroom and use toilet paper temporarily, then visit the school nurse who will have pads available. Keeping a small supply of pads in your backpack is a great way to be prepared just in case.
