First period guide: preparing your daughter

Short answer: most girls get their first period between 10 and 15, usually about two years after their breasts start to develop. The best preparation is a calm, early conversation before it happens, a small kit in her school bag with two pad sizes and spare underwear, and a simple plan so she knows what to do if it starts while she is away from home.

A first period is a big moment for a girl, and often for her mother too. Many of us remember going through it with very little information, and want something calmer for our daughters. We wrote this guide for you first, and it is written so your daughter can read it with you.

When does the first period come, and what are the early signs?

Most girls get their first period between 10 and 15, at an average age of 12, according to KidsHealth. The NHS puts the range wider, anywhere from 8 to 17, so there is no need to compare her with her friends or sisters.

Signs that the first period is getting close:

  • Breast development: the first period usually comes about two years after the breasts start to grow (NHS, KidsHealth).
  • Underarm and pubic hair: the NHS lists these as signs a period is on its way.
  • White discharge: it usually starts six months to a year before the first period (KidsHealth). The Saudi Ministry of Health describes normal discharge in puberty as clear white or yellowish, without a bad smell or itching.
  • Other changes: growing taller and heavier, rounder hips, spots, and more sweating, all listed by the Ministry of Health as part of puberty in girls.

Once you notice these signs, it is a good time to put her kit together and start the conversation if you have not already.

How to start the conversation

KidsHealth advises starting early and building on her understanding little by little, answering questions simply and directly. It does not have to be one big talk. A few ideas that make it easier:

  • Use everyday moments: when you are buying pads, when she asks about a change in her body, or when she mentions a friend has started.
  • Pick a quiet, private time: in the car or at bedtime, away from siblings and guests.
  • Start with your own story: "I remember my first period..." takes the awkwardness out and tells her this happens to every girl.
  • Keep the door open: tell her any question is fine, at any time, and if you do not know the answer you will find it together.
  • If you feel shy: that is fine. A book written for her age, a relative you trust, or a doctor or nurse can help, as KidsHealth suggests.

Many families also talk with their daughters about the religious side, such as the rules on prayer and fasting during a period. These are important questions for her, and they are best answered by you or by someone your family trusts on these matters, such as her religion teacher or a knowledgeable relative.

What to explain, simply

  • What a period is: blood that leaves the body from the womb about once a month. The Ministry of Health describes it as a sign that the body is healthy and normal.
  • How long it lasts: on average 3 to 5 days, sometimes up to 8 or 10, and it differs from girl to girl (Ministry of Health).
  • It is less blood than it looks: about 20 to 90 ml over a whole period, roughly 1 to 5 tablespoons, and it does not come all at once (NHS).
  • Irregular at first is normal: the first period may be short, and she may skip a month or more afterwards. The Ministry of Health says a girl's body usually needs about two years for periods to become regular.
  • Nobody knows unless she tells them: a period does not show on her face, it is nothing to be ashamed of, and her privacy is hers to keep.
  • What to do if it starts suddenly: go to the bathroom, put on a pad from her kit, and tell you, the school nurse, or a teacher she trusts.

A first period kit for her school bag

The NHS and Cleveland Clinic both suggest carrying supplies before the first period arrives, so it does not catch her out at school. A small pouch in her school bag is enough:

  • Day Pads 180mm, no wings: for light days and the start and end of her period.
  • Day Pads 260mm with wings: for school days; the wings hold the pad in place through movement and long hours of sitting.
  • Spare underwear in a small sealed bag, as the NHS recommends.
  • Unscented wipes, and a small bag for used pads in case there is no bin nearby.
  • A small pouch in a plain colour that does not draw attention, to keep it all together.
  • Optional: a light jacket or cardigan she can tie around her waist if her clothes get stained, an idea from Cleveland Clinic.

Every Blossom Wings pad is individually wrapped, so they are easy to carry. If you are unsure which size she needs, see our pad size guide.

School day tips

  • Change the pad at break times and whenever she gets the chance, even if it is not full.
  • Wrap the used pad in the new pad's wrapper or a tissue and put it in the bin, never in the toilet.
  • Wash hands before and after changing.
  • Know where the school nurse is. If she runs out of pads, it is fine to ask a teacher or the nurse, as the NHS advises.
  • Carry on with the day as normal: lessons, walking and light activity are all fine.

The first nights

At night she sleeps for long hours without changing, and may turn a lot in her sleep, so she needs longer protection:

  • Night Pads 330mm with wings: longer than day pads, made for heavy flow and long hours of sleep.
  • Comfort Panties: disposable period underwear worn exactly like normal underwear, with no adhesive and no pad to shift. They can be easier for the first nights because there is no pad to learn to position.
  • Check the size: Comfort Panties come in S/M. Check the size information on the product page before you order, especially if she is slim or petite, because loose underwear does not sit snugly.
  • Lay a dark towel over the sheet for the first few nights so she can sleep without worrying about leaks.

Pain: what is normal, and when to see a doctor

Cramps are common. The NHS describes them as pain or cramps in the tummy that start just before or at the start of a period, and can spread to the back and thighs. What usually helps, according to the NHS:

  • A hot water bottle wrapped in a towel on her tummy, or a warm bath or shower.
  • Gentle movement such as walking.
  • A simple painkiller such as paracetamol or ibuprofen. Ask a pharmacist about the right dose for her age and weight.

See a doctor if you notice any of the following (KidsHealth, Cleveland Clinic, NHS):

  • Severe pain that painkillers do not relieve, or pain that stops her going to school or doing her usual day.
  • Very heavy bleeding that soaks through a pad in less than two hours.
  • Bleeding that lasts longer than 10 days.
  • She is 15 and has not had a period, or her breasts started developing more than 3 years ago and her period has not come.
  • Her period started before age 9.
  • More than two years after her first period, her periods still do not come roughly every 3 to 6 weeks, especially if she misses three or more in a row.
  • Discharge with a bad smell or itching, since the Ministry of Health describes normal discharge as having neither.

Track her cycle together

Because periods are irregular at first, writing them down helps you both learn what is normal for her. Note the start date, how many days it lasts and any pain, and take these notes if you see a doctor. You can use the Blossom Wings period tracker to estimate when her next period is due and pack her kit ahead of time.
