I Just Got My First Period. What Do I Do?
Your first period does not need a plan you already have memorised. Here is exactly what to do right now, and in the days that follow.
Published 27 July 2026
Something to catch the flow, one person you trust to tell, and today's date written down. That is everything you need in the first few minutes. You can work everything else out as you go.
This page covers exactly that: the first hours. For the fuller picture of what counts as normal, and when to see a GP, see your first period: everything you need to know.
The first five minutes
Fold some toilet paper, a flannel or a spare piece of fabric into a pad shape and place it in your underwear. It will hold the flow until you can reach a proper pad or tampon.
This works, and it is normal to need it. A first period is rarely a sudden flood. The NHS describes it as more often a small reddish-brown stain than a gush. A folded wad of tissue, kitchen roll or a rolled-up sock is a genuine stopgap. There is no need to feel embarrassed about using it. If a pad, tampon, period pants or a menstrual cup is nearby, use it instead. All of these are safe and suitable from your very first period. Wash your hands before and after. Once you are sorted, the panic usually settles fast. When the rush has passed, it is worth comparing pads, tampons, period pants and cups properly so you know what suits you.
Telling someone
Tell one adult you trust, in as few words as you like. "I think I've started my period" is enough. Feeling awkward saying it is completely normal, and it gets easier the second it is said.
The NHS recommends talking to a parent or another trusted adult about what to expect. Ideally you would do this before it happens, but right now works just as well. A text message is a fine way in, something like "I started my period, can you get me some pads." So is writing a note and handing it over, or telling a school nurse, a form tutor or a friend's mum. You do not owe anyone an explanation beyond the fact itself. Every trusted adult has either been through this themselves or has helped someone else through it. It is well-trodden ground for them, even if it is brand new for you. If the nerves linger after today, our article it's okay to feel nervous about your first period explains why that is the norm, not the exception.
At night
Wear a night pad, period pants, or both, and slide an old towel under your bottom sheet if you are worried about leaks. You do not need to change how or where you sleep.
Night pads and period pants are built wider and more absorbent for exactly this reason, so they cover more ground than a daytime pad while you are lying down. A tampon is not the easiest overnight choice for a first period. NHS guidance is not to leave a tampon in longer than recommended, and that is hard to judge while you are asleep. A pad or period pants are the simpler option until you have a routine sorted. Sleeping on your front, back or side makes no difference. If a small leak does happen, it is only fabric, and it washes.
Away from home
Ask a friend, a teacher, a shop assistant or someone nearby you trust. Most people will have something on them or can point you to a toilet with a vending machine. A jumper tied round your waist covers any mark on your clothes.
Public toilets, cafes, shops and school offices are used to being asked this exact question. There is no need to overthink who to approach. If this happens during the school day, there is a full calm plan for that, including the exact words to use with a teacher or the school nurse.
What the first few days look like
Your first period is often shorter than the ones that follow. It can take several months for a regular pattern to settle in.
Total blood loss across a whole period is typically 20 to 90ml, about 1 to 5 tablespoons, according to the NHS. The blood is red when the flow is heaviest, and can be pink or brown on lighter days. None of this is anything to worry about. Your first period might not last very long. It can take your body some months to settle into a regular pattern. Once it does, the NHS describes a typical settled cycle as a period every 23 to 35 days, lasting 2 to 7 days. Until then, gaps between periods can vary a lot. That is expected, not a sign that anything is wrong.
Note the date
Write down the day your bleeding started. That is day one of your cycle, the number that every period diary, app and doctor counts from.
The NHS defines the menstrual cycle as the time from the first day of one period to the day before the next period starts. That makes the first day of bleeding the anchor point for everything that follows. Your first cycles may be irregular, but noting that one date still builds a useful habit. It helps you track your own pattern, and it helps you answer a GP's first question accurately if you ever need to.
None of this needs an app, a plan, or anything more than what is already in the bathroom cabinet. When you are ready to keep a record, Simply Track's setup includes a first-period option. It opens straight into a gentle, step-by-step guide covering pads, tampons, cups and more, and that guide is always free. Logging the date is optional, but it is the one habit that makes every period after this one easier to understand.

Common questions
Do I need to tell my parents I've started my period?
There is no rule that says you must, but the NHS recommends talking to a parent or another trusted adult, since they can help with pads or tampons and explain what to expect. A carer, older sibling, school nurse or teacher counts just as well if that feels easier.
What if I have nothing with me when it starts?
Folded toilet paper, tissue or a rolled-up sock in your underwear will hold the flow for a while. Ask a friend, teacher or school nurse, schools often keep spares and so do many public toilets, or a nearby shop will sell pads and tampons.
Does a first period hurt?
It might. The NHS says pain or discomfort before or during a period is common, usually cramping low in the tummy. Paracetamol or ibuprofen, a hot water bottle and gentle movement all help. See a GP if the pain stops you doing your usual day.
