The short answer: Most girls get their first period around the age of 12, but anywhere from 8 to 17 is normal. It usually comes about two years after your breasts start to grow. Other clues that it's getting close are hair under your arms and between your legs, a growth spurt, and white or clear discharge in your underwear. Your body has its own timetable, so starting earlier or later than your friends is completely fine.
What is a period, in simple words?
Inside your tummy, below your belly button, is a small organ called the womb, or uterus. Every month, its inside lining gets a little thicker, ready in case a baby ever grows there when you are an adult. When that doesn't happen, the lining isn't needed, so your body lets it go.
The lining comes out as blood through your vagina, which is the opening between your legs, over a few days. That's your period. Doctors call the very first one menarche (say it "men-AR-kee").
A period is not an injury and it isn't dirty. It's a sign that your body is healthy and growing up the way it should.
At what age do girls get their first period?
The NHS says first periods usually start between the ages of 8 and 17, and the average is around 12. That's a very wide range, and every age inside it is normal.
Some girls start in Class 4 or 5, others in Class 10. Your body isn't racing anyone.
Can I guess when mine will come?
Nobody can give you an exact date, but two things help you make a good guess:
- Your breasts. Periods usually start about two years after your breasts begin to develop. The first sign is often a small, tender bump under one or both nipples, sometimes called a breast bud.
- Your family. Many girls get their first period at about the same age their mother did. It's worth asking your mum, or an older sister, when theirs started.
If your breasts started growing when you were 10, for example, your period might arrive somewhere around 12. It could be a few months earlier or later, so it's a guide, not a promise.
Signs your first period is coming
Your body gives you lots of hints in the year or two before your first period. Puberty, the time when your body changes from a child's to an adult's, happens step by step. You may notice some of these:
Breast development
Breast buds are usually the first change of puberty. One side may grow faster than the other for a while, and they can feel sore or itchy. This is normal. A soft cotton slip or beginner bra can feel more comfortable under a school uniform.
Body hair
Hair starts to grow in your pubic area (between your legs) and later under your arms. It's often soft and light at first and gets darker and curlier over time.
A growth spurt
Many girls grow taller quickly in the year or so before their period. Your hips may get a little wider and your body shape may become curvier. Your school uniform might suddenly feel short or tight.
White or clear discharge
Discharge is a fluid that comes from your vagina and keeps it clean and healthy. In the months before your first period, you might notice white, creamy or clear marks in your underwear. This is one of the best clues that your period isn't far away. Normal discharge doesn't smell bad or make you itchy. You can read more in our guide to normal vaginal discharge through the month.
Skin, sweat and moods
Hormones, the body's chemical messengers, can cause spots on your face, oilier hair and stronger-smelling sweat. You might also feel more emotional, cry more easily or feel grumpy for no clear reason. That's not you being difficult. It's your hormones settling in.
@@TABLE Sign|What you might notice|What it tells you ;; Breast buds|Small, tender lumps under the nipples|Period likely in about 2 years ;; Pubic and underarm hair|Soft hair that slowly gets darker|Puberty is well under way ;; Growth spurt|Taller quickly, wider hips, clothes feel small|Often in the year before your period ;; White or clear discharge|Creamy or clear marks in your underwear|Period may be a few months away ;; Tummy ache or bloating|Dull ache low in your tummy or back|Can happen just before a period ;; Spots and moods|Oilier skin, mood swings, feeling tired|Hormones are changing @@What will my first period look like?
Many girls imagine a sudden rush of bright red blood. In real life, a first period is usually much gentler than that.
- Colour: it might be brown, pinkish or red. The NHS describes a reddish-brown stain on your pants or sheets. Brown is very common, because older blood turns darker. Our period blood colour chart explains what each shade means.
- Amount: often only a little. Some girls just see a few spots. It looks like more than it is when it spreads on fabric.
- How long: anywhere from 2 to 7 days. A first period can also be very short.
- How it feels: bleeding itself doesn't hurt. You might feel a dull ache in your lower tummy or back, which is called a cramp.
You may first notice it on the toilet, or as a mark on your sheets. It's not an emergency. Change into clean underwear and use a pad or period panty.
Will my periods be regular straight away?
Probably not, and that's normal. For the first year or two, your body is still learning its rhythm. Your second period might come three weeks later, or not for two or three months.
Adults usually have a period every 21 to 35 days. The NHS says most girls have regular periods by the age of 16 to 18. Until then, being early, late or skipping a month now and then is common.
A good habit is to mark the first day of every period on a calendar or in a free period app. After a few months you'll start to see your own pattern. Our guide on how to calculate your next period date shows you how, with simple examples.
What should I use for my first period?
There's no single right answer. Most girls start with pads or period panties because they are easy and go outside the body. The NHS notes that pads are a good choice for a very first period, as tampons and cups can take some getting used to.
@@TABLE Option|What it is|Good to know ;; Pad|A soft strip that sticks inside your underwear and soaks up blood|Easy to use; change every few hours, or sooner if it feels full ;; Period panty|Underwear with a built-in absorbent layer|Feels like normal underwear; nothing to stick or adjust; can be worn for up to 8 hours depending on flow ;; Panty liner|A very thin pad|Good for discharge, spotting or the last light days ;; Tampon or cup|Goes inside the vagina|Safe, but needs practice; many girls try these later @@Period panties are popular with girls who play sport, travel by bus or worry about a pad moving during class. Fabpad's Period Panty for Teens has a 5-layer absorbent core and comes in age-based sizes from 10 to 12 years up to 18 to 20 years, in colours like black, navy and maroon that hide marks well.
It's a good idea to try a pad or period panty at home before your period comes, so you know how it feels and how to put it on. Ask your mum or an adult you trust to show you.
Get ready before it happens
Being prepared is the best way to feel calm. A small zip pouch in your school bag, kept there all the time, means you're never caught out. Put in:
- Two pads, or a spare period panty
- A spare pair of regular underwear
- A small zip bag or paper bag for anything used
- A few tissues or gentle wipes
- A dark cardigan or sweatshirt you can tie around your waist if you leak
If you'd like a full list for home, school and sleepovers, our first period checklist covers everything step by step.
If it starts at school
Go to the toilet and check. If you have your pouch, use a pad or change into your spare. If not, fold some toilet paper into a thick strip as a pad for now. Then ask a teacher, the school nurse, the warden or a friend for a pad. Lots of girls start at school, and teachers have helped many before you. More tips are in our school guide for teens.
Looking after yourself during your period
- Change regularly. Change a pad every few hours, or sooner if it feels full. A period panty can be worn for up to 8 hours, depending on your flow.
- Bathe as usual. A shower or a bucket bath is completely fine, and it helps you feel fresh. Wash the outside of your vagina with plain water. You don't need soap or anything inside.
- Eat well. Iron helps your body replace blood. Foods like dal, palak, rajma, chana, ragi, eggs and jaggery are good choices, along with plenty of water.
- Ease cramps. A hot water bottle wrapped in a towel, a warm bath, gentle stretching or a short walk can help. If the pain is strong, ask a parent about a painkiller such as paracetamol or ibuprofen, and check the packet or ask a pharmacist first.
- Throw pads away properly. Wrap a used pad in its wrapper or paper and put it in the bin. Never flush it down the toilet.
Feelings, family and talking to someone
It's normal to feel excited, nervous, proud, embarrassed or all of these at once. All of these feelings are okay.
Talking really helps. You could talk to your mum, an older sister, a chachi, mausi or bua, a grandmother, your dad, a teacher or the school counsellor. Choose whoever feels easiest. If you're shy, you could start with "Can I ask you something private?" or even write a note.
Some families have traditions around periods, such as a small celebration or rules about certain activities. It can help to ask your family what they follow and why. Whatever the customs at home, remember the facts: periods are clean, healthy and normal, and you deserve to feel comfortable and respected.
See a doctor if
Tell a parent or trusted adult, and see a doctor, if:
- You're 15 and your periods haven't started yet
- You're 13 and you have no other signs of puberty, such as breast growth or body hair
- You started showing signs of puberty, like breasts or pubic hair, before the age of 8
- Your period is so heavy that you need a new pad every 1 to 2 hours, or blood soaks through to your clothes or bedding
- You pass blood clots larger than about 2.5cm, roughly the size of a ₹10 coin
- A period lasts more than 7 days
- Cramps are so bad that you have to miss school or can't do normal things
- You feel very tired, weak or short of breath a lot
A doctor will usually just talk to you, check your height and weight, and maybe suggest a blood test. A parent can stay with you. Our guide on how much bleeding is too much explains more about heavy periods.
Get urgent help if
Call 112 or 108, or go to the nearest hospital emergency department, if you are bleeding very heavily and feel faint, dizzy or very unwell, or if you have sudden, severe tummy pain that painkillers don't help, especially with a fever or vomiting.
Frequently asked questions
Is it normal to get my period at 9? Yes. Periods can start from 8, so 9 is within the normal range. If you noticed breast growth or pubic hair before you turned 8, it's worth a check-up with a doctor.
I'm 14 and haven't started. Is something wrong? Usually not. Many girls start at 14, 15 or later. If you have breast growth and body hair, your period is probably on its way. See a doctor if you reach 15 without a period, or 13 with no signs of puberty at all.
How long after discharge starts will I get my period? There's no exact time, but many girls notice discharge in the months before their first period. It's a sign your body is getting ready.
Does the first period hurt? The bleeding doesn't hurt. Some girls get a mild tummy ache or back ache, and some feel nothing at all. Warmth and gentle movement usually help.
Can I bathe or wash my hair during my period? Yes. Bathing is safe and a good idea during your period. Washing your hair is completely fine too.
My period came once and then stopped for two months. Is that okay? Yes, that's very common in the first year or two. Your body is still finding its rhythm.
Will people know I'm on my period? No, not unless you choose to tell them. Pads and period panties can't be seen under your clothes or uniform.
