## Quick answer

- First periods usually arrive around age 12 but can start anywhere from about 8 to 17.
- Light, brown or irregular early periods are normal.
- See a GP if there is no period by 15 (or by 13 with no other signs of puberty).
- You can use any period product you like from the start.

Your first period, called [Menarche](https://splash.care/learn/glossary#menarche), is a big milestone, and it is completely normal to feel excited, nervous, or a bit "meh". Periods usually start around age 12, though the NHS says anywhere from about 8 to 17 is within the usual range.

## Clues it might be coming

- [Breasts](https://splash.care/learn/body-literacy/breast-changes) started growing. The first period usually comes about 2 years later (ACOG says 2 to 3 years).
- Pubic and underarm hair.
- White or yellowish [discharge](https://splash.care/learn/body-literacy/discharge-decoded) in your underwear, often months before.

## What it might look like

First periods are often light, and can be brown, pink or red. You might only see a reddish-brown stain on your pants or sheets, not a sudden gush. The whole period is only about 20 to 90 ml (1 to 5 tablespoons). It is normal for periods to be [irregular](https://splash.care/learn/cycle-basics/irregular-cycles) for the first year or two, and ACOG says it can take several years for cycles to settle. Cycles of 21 to 45 days count as normal in teens.

## Which product should I use?

It is up to you. The NHS says [pads](https://splash.care/learn/period-care/products-compared), tampons, menstrual cups and period pants are all safe and suitable from your very first period. Many people start with pads because tampons and cups take a bit of getting used to. A tampon cannot get lost inside you, and you can take it out with the string at any time.

> **Splash says:** pop a "just in case" kit in your bag: a pad or two, spare pants and a small bag. If you get caught out at school, you can ask a teacher or the school nurse for a product. They have heard it all before.

### When to see a doctor

The NHS says see a GP if you have not started periods by 15, or by 13 if you have no other signs of puberty such as breast growth. Also see a doctor if periods last more than 7 days, are very heavy (soaking through a pad or tampon every 1 to 2 hours), or are very painful and stop you doing normal things.

**Myth:** You cannot use tampons or a cup when you are a teen.

**Fact:** The NHS says tampons, cups, pads and period pants are all safe from your first period. Start with the smallest size, read the instructions, and ask an adult you trust if you are unsure.
