What are the signs your first period is coming?
The clearest signs your first period is coming are breast development that started about 2 to 3 years earlier, and white or clear discharge in your underwear, which often appears 6 to 12 months before. Pubic and underarm hair, a growth spurt, spots and moodiness are other clues. Most people get their first period between 10 and 15, around age 12.
The signs, in rough order
| Sign | Usual timing before a first period |
|---|---|
| Breast buds (small bumps under the nipples) | About 2 to 3 years |
| Pubic hair, then underarm hair | 1 to 2 years |
| Growth spurt | Fastest growth is usually just before the first period |
| White or clear discharge | About 6 to 12 months |
| Spots, oilier skin and hair | Often in the months before |
| Mood swings, feeling emotional | Can appear in the months and days before |
| Cramps, bloating, sore breasts | Sometimes in the days before |
Everyone's body has its own timetable, so these are rough guides. Some people get spots for years first; others notice discharge only a few weeks before. Breast development that started more than 3 years ago is one of the more reliable clues that a period isn't far off.
What age to expect it
Most people get their first period between 10 and 15, with the average around 12. Starting at 8 or as late as 15 can still be normal. Family history matters: people often start around the same age their mother or sisters did. See what age you get your first period.
How to get ready
- Keep a pad or period underwear in your school bag, just in case.
- Know who you can ask for help at school: a teacher, nurse or friend.
- Practice using a pad at home so it feels familiar.
- Learn what's normal: a first period is often light and brownish, and may only last a couple of days.
- Don't worry if the next one doesn't come for a few months. Early cycles are often irregular.

Feelings before a first period
The hormones that start your cycle also affect how you feel. Feeling more emotional, cross or teary than usual, or wanting time alone, is very common in the months around your first period. It doesn't mean anything is wrong. Once periods start, tracking how you feel can show you which days of the month tend to be harder, which makes them easier to handle.
You haven't had a period by 15, it's been 3 years since your breasts started developing and there's no period yet, signs of puberty started before 8, or your first periods are so heavy you soak a pad every hour or feel dizzy.
