Soso Answers: Period Products, Missing Cramps and New Expectations (August 22 to 28)

Every week, girls ask Soso questions in the app, and every week a few of them turn up again and again. This week the questions clustered in a way we have not seen before. A lot of you were standing in front of a shelf of products with no idea which one to pick. A few of you had just started, that day or that week, and wanted to know what happens next. One question was the opposite of what we usually get: not "why do my cramps hurt" but "why do I not have any". Several of you were worried less about your body and more about what everyone around you would expect once your period arrived. And one of you had a dream about it.

Here are the five we heard most, answered properly. Nothing here is a quote. Every question is paraphrased and every detail that could identify anyone has been left out.

What should I use for my first period, and what else is out there besides pads?

This was easily the biggest theme of the week. Several girls asked which product to start with. Others asked what the options even are beyond pads, and one asked specifically about sports where you move fast or end up upside down, like volleyball, running, aerial and swimming.

What is going on

Every period product on the shelf does one of exactly two jobs. It either catches blood outside your body, or it collects it inside your vagina.

• Catching, on the outside: pads, which stick to your underwear; period underwear, which has the absorbent layer built in so there is nothing to stick on; and reusable cloth pads, which you wash instead of binning.
• Collecting, on the inside: tampons, which absorb the blood; menstrual cups, which are small flexible cups that hold it instead of soaking it up; and menstrual discs, which sit slightly differently but do the same job.

That is the whole map. There is nothing else to learn.

One thing is worth knowing before you go anywhere near an internal product, because it is behind a lot of the worry: nothing can get lost inside you. Your vagina is not an open tunnel into your body. It is a closed passage that ends at your cervix, and the opening in the cervix is far too small for a tampon or a cup to pass through. This is also the answer to the sports question. Hanging upside down on aerial silks does not make a tampon or a cup travel anywhere or fall out, because there is nowhere for it to go and it is held by the walls of your vagina, not by gravity.

What the research actually says

Because so many of you asked about cups specifically, including how big they actually are, this is where the real evidence is worth quoting.

The largest review we have is by van Eijk and colleagues, published in The Lancet Public Health in 2019. They pulled together 43 studies covering 3,319 women and girls. Here is what they actually found:

• On size and capacity: cups in the studies held between 10 and 38 millilitres, and were emptied every 4 to 12 hours. So there is no single answer to "how big is a cup". They vary, and brands sell more than one size for that reason.
• On leaking: four of the studies compared cups directly against pads and tampons, with 293 participants between them. Leaking was similar or lower with cups.
• On safety: three studies examined 370 users and found no abnormalities. Across the whole body of literature the reviewers counted a small number of serious problems, including five cases of toxic shock syndrome. That is rare, but it is not zero, which is why the instructions on the box about clean hands and emptying on time matter.
• On the learning curve, which is the part nobody tells you: pooled across the studies, about 3 in 100 users could not insert the cup at all, about 20 in 100 reported discomfort on insertion, and about 11 in 100 stopped using it. The difficulty is front-loaded: 35 in 100 reported it in the first cycle, dropping to 13 in 100 by later cycles. The reviewers also describe a learning curve of two to five months, though that figure comes from longitudinal studies in low- and middle-income countries, so treat it as a rough sense of scale rather than a number that applies to you.

Be careful with those numbers, because the authors themselves are. They rated the quality of the quantitative studies as low, with only two of moderate to high quality. The studies varied enormously, almost everything relied on people reporting on themselves, and some used older cup models. So: cups work, cups are broadly safe, and cups take a while to get the hang of. That is as far as the evidence goes.

What to do about it

1. Start with a pad or period underwear. Not because internal products are bad, but because on day one you have enough going on. A pad asks nothing of you except sticking it in your underwear the right way round.
2. Give yourself one product for at least two or three cycles before you judge it. Almost every "this is horrible" reaction on day one is really a reaction to it being new.
3. When you want to try something internal, try it on a medium-flow day, at home, with time. Not before school, not before a match. Wash your hands first. If it hurts, stop and try again next cycle. Pain on a first try is usually about angle or tension rather than anything being wrong. But if it hurts badly every time, even after several unhurried attempts, tell an adult, because there are a few ordinary and treatable reasons a tampon may not go in comfortably.
4. For sports, pick by how much you move, not by the sport's name. Running, gymnastics and aerial move you in every direction, so an internal product or period underwear stays put better than a pad, which can shift. For swimming, a pad will not work because it soaks up pool water, but a tampon works, a cup works, and so does period swimwear, which is made from absorbent fabric and means you do not have to insert anything at all.
5. If you want to try a cup, plan for a slow start. Decide in advance that the first two cycles are practice, and keep pads as your backup during those cycles so a bad attempt never becomes an emergency.
6. Ask an adult before you buy anything internal, especially a cup. Not for permission to have a period, but because cups cost real money, come in sizes, and it helps to have someone who can go and get a different one if the first is wrong.

A worked example

Imagine your period is due in the next week or two and you have no idea what to use.

You buy a pack of regular pads and one pair of period underwear. Your first period arrives on a Tuesday. You use pads on Tuesday and Wednesday, because they are the least demanding thing in the world. You wear the period underwear to bed on Wednesday night and discover you sleep better because there is nothing to shift.

By Thursday your flow is lighter and you have swimming on Saturday. You decide not to make Saturday the day you learn a new skill, so you sit that one out and plan to try a tampon on a calm afternoon during your next period instead. Next cycle, on a quiet Sunday, you do. It takes three goes. On the third it slides in and you cannot feel it, and swimming is back on the table. That is what an unhurried version of this looks like.

When it is more than a product question

First, the two rules that come with internal products. Never leave a tampon in for more than 8 hours, and change it every 4 to 6 hours. Empty a cup at least every 12 hours. Take an internal product out and get an adult straight away if, while wearing one, you get a sudden high temperature, chills, vomiting or diarrhoea, a rash that looks like sunburn, or dizziness or confusion. That combination is rare, but it is an emergency, not a wait-and-see. The adult should ring a doctor or the emergency number right then and say you were using a tampon or a cup. If you also feel confused, faint or short of breath, that is an ambulance, straight away.

And if you cannot get a tampon or a cup out, that is not a problem to solve alone or in silence. Tell an adult. A doctor or nurse can remove it easily, and it happens often enough that nobody will be surprised.

Beyond that, talk to an adult you trust if you are having to change a pad or tampon every one to two hours, if your bleeding lasts longer than seven days, if you feel dizzy, faint or short of breath, or if an internal product hurts badly every single time even after several unhurried attempts. Those are worth checking, and none of them are your fault.

I just got my first period. What do I actually do now?

Two girls this week wrote in on the day it happened, essentially asking: right, it is here, what am I supposed to do?

What is going on

The lining that built up inside your uterus over the past few weeks is leaving. That is the whole event. It usually lasts a few days, it is usually heaviest at the start, and the blood often looks brown at the beginning and the end because blood turns brown when it meets air and leaves slowly.

The part nobody warns you about is what happens after. Your first period is not a switch that turns on a monthly schedule. In the first year or two, a lot of cycles happen without an egg being released, and cycles without ovulation are the ones that turn up whenever they feel like it. So a long gap after your first period is extremely common and is not a sign that something broke.

What the research actually says

Paula Adams Hillard, writing in the Medscape Journal of Medicine in 2008, sets out the ranges doctors actually use for teenagers. A normal cycle in the first couple of years runs roughly 20 to 45 days, with an average of about 32 days. Most teenagers bleed for 3 to 7 days, and bleeding longer than 7 days is uncommon enough to be worth getting checked. She also makes a point that matters here: the 95th percentile for cycle length is 90 days even in the first year, which is the evidence-based line for "this gap is now long enough to mention to a doctor".

On how long the unpredictable phase lasts, Carlson and Shaw reviewed this in the Journal of Pediatric and Adolescent Gynecology in 2019. They report that in the first one to two years after a first period the majority of cycles happen without ovulation, but they are honest that studies disagree with each other on the exact numbers, and that there is a lot of variation between individual girls. So the useful takeaway is the direction, not a percentage: early cycles are irregular by design, and they settle.

One more finding is worth knowing. Marván and colleagues, writing in the Journal of Pediatric and Adolescent Gynecology in 2012, surveyed 405 girls aged 12 to 15 and found that only 39% felt prepared for their first period. Girls who had talked with their mothers about the emotional side beforehand, not just the biological facts, were far more likely to feel prepared. That was one country and one sample, so treat the exact number carefully, but the pattern is clear: it is the conversation about feelings that makes the difference, not the diagram.

What to do about it

1. Right now: put on a pad, and put two spares plus a spare pair of underwear in your bag. That is the entire emergency plan and it works.
2. Write down today's date. Or better, log it in the app. Your first date is the anchor for everything you will notice later.
3. Tell one adult. You do not have to make an announcement. "I got my period today" is a complete sentence. If saying it out loud is too much, write it on a note or send a message. It counts the same.
4. Change your pad every few hours even if it looks like there is barely anything on it. This is about staying fresh, not about capacity.
5. Expect it to be lighter than you imagined. Many first periods are a few spots of brown for a day or two. That still counts as your first period.
6. Do not expect it back in exactly a month. Expect it back somewhere in a wide window, and let the app do the remembering.
7. Keep doing your normal things. You can shower, wash your hair, swim with an internal product, run, sleep normally and go to school. There is no activity on this list you have to give up.

A worked example

Say it starts on a Wednesday at school. You notice in the bathroom. You get a pad from the school nurse or a friend, because asking is faster than panicking, and you tie your jumper round your waist if that helps you feel less watched, though almost certainly nobody can see anything.

At home you tell whichever adult is easiest to tell first, even if that is not the one you think you are supposed to tell. You log the date. Thursday and Friday are lighter. By Saturday it is done, and the weekend goes ahead exactly as planned.

Then nothing happens for six weeks and you start wondering if you imagined it. You did not: that gap is squarely inside the normal range for a first year.

When it is more than a normal start

Tell an adult if any of these turn up:

• You are having to change a pad or tampon every one to two hours, you are passing clots bigger than about two and a half centimetres across, or you bleed through onto your clothes or bedding.
• Bleeding goes on past seven days.
• You feel tired, dizzy, faint or short of breath a lot.
• Ninety days go by with no period at all after your first one.
• And if you are using a tampon or a cup and you suddenly get a high temperature, feel shivery or achy, are sick, or get a rash like sunburn, take it out and tell an adult straight away. This is rare, but it needs to be seen the same day, not tomorrow.

None of these mean you did something wrong, and asking about them is not overreacting.

Why do I not have cramps? Is something wrong with me?

One girl asked why she does not get cramps, and it was clear she was worried that missing a symptom meant her body was doing something wrong. It is the reverse of the question we usually get, and it deserves a real answer.

What is going on

Cramps happen because your uterus is a muscle. Chemicals called prostaglandins make that muscle squeeze to help shed the lining. Stronger squeezing briefly reduces blood flow inside the muscle, and that is what you feel as pain. Prostaglandins also turn up the volume on pain signals generally, which is why the same period can bring backache and an unhappy stomach at the same time.

Here is the part that answers your question: how much your body produces, and how much you feel it, varies enormously from person to person. Having very little pain does not mean nothing is happening. It means your particular body is doing the same job with less commotion.

What the research actually says

Two things, and they fit together neatly.

First, period pain is common but nowhere near universal. De Sanctis and colleagues, in Pediatric Endocrinology Reviews in 2015, found reported rates in adolescents ranging from 16% to 93% depending on the population studied and how the question was asked, with severe pain in 2% to 29%. That range is enormous and we are not going to pretend otherwise. What the studies agree on much more closely is severe pain: 2% to 29%. So severe period pain is very much a minority experience, and how much any given person hurts varies hugely. McKenna and Fogleman, in American Family Physician in 2021, put overall dysmenorrhea at 50% to 90% of adolescents and women, which is a broad clinical figure rather than a pooled one.

Second, and this is the piece that explains the timing: McKenna and Fogleman state that primary dysmenorrhea, the ordinary kind of period pain, begins on average six to twelve months after a first period, corresponding with the start of cycles where an egg is released. So if you started recently and have no cramps, that is exactly what the medical literature would predict. It also means cramps can show up later, usually somewhere around six to twelve months in, and that is your cycles maturing rather than anything going wrong. Pain that turns up long after that, or that gets worse cycle after cycle, is worth a doctor's look instead.

What to do about it

1. Do not go hunting for it. Expecting a symptom can make you notice every twinge, so log what you actually feel rather than what you were told to expect.
2. Track anyway. Painless periods still have a pattern worth knowing: how many days, how heavy, how you sleep, how your mood moves.
3. Learn what helps before you need it. If pain arrives in a year, you want to already know that a heating pad works, that gentle movement helps, and who you would tell.
4. Say the true thing when friends compare. Something like: "Mine do not really hurt. I know that is lucky." You do not have to invent cramps to belong in the conversation.
5. If cramps do start later, do not treat it as normal to suffer through them. Tell an adult early. Pain that stops you doing things is worth managing, not enduring.
6. On pain relief, if it becomes relevant: the timing matters more than most people realise. McKenna and Fogleman note that medication works best when it is started one to two days before bleeding and continued through the first two or three days, tracking when prostaglandins peak. But the medicine and the amount are decisions for a parent, carer or doctor who knows your age and weight. Never work that out on your own.

A worked example

Say you have had four periods and none of them have hurt.

You log each one anyway. You notice yours run about five days, that day two is the heaviest, and that you are unusually tired the day before it starts. That is a useful pattern and it is entirely yours.

Eight months later a period arrives with a real ache low in your belly for the first time. Because you have been tracking, you are not frightened by it. You know it is your seventh period, you know the literature expects pain to show up somewhere around here, and you already know a heating pad is in the cupboard. You mention it to a parent that evening rather than three cycles later.

Nothing went wrong in that story. Your body did what bodies do.

When it is more than a quiet period

Missing cramps is not itself a warning sign. But do speak to an adult if your periods stop for 90 days after they had been coming, if you are having to change a pad or tampon every one to two hours or soaking the bed at night, if you feel dizzy, faint or short of breath, if bleeding lasts longer than seven days, or if pain arrives later and is severe enough to keep you home from school or gets worse cycle after cycle. That last one is worth a doctor's opinion, not a supply of painkillers.

What if getting my period changes what is expected of me at home?

A few girls this week were not worried about blood at all. They were worried about what the people around them would do once they knew. One asked how to bring up something with a parent that she expected to be met with new rules. Another asked how to raise a request with a parent at all. Underneath both is the same thing: your period is a private body event, but in a lot of families it is also treated as a public milestone.

What is going on

In many families and cultures, a first period is not just a biological fact. It is a marker of moving from being a child to being something else, and families respond to that with new expectations: different clothes, different rules about where you go and with whom, new religious or cultural steps, more responsibility at home, or simply being talked to differently.

None of this is invented and none of it means your family is doing something wrong. Traditions around menarche are old and often loving. But it is completely reasonable to feel that your body has changed faster than you have, and to want a say in the pace of everything else.

What the research actually says

The evidence here is smaller and more specific than the evidence about cramps, so we will be careful about what it can and cannot tell us.

Gold-Watts and colleagues, writing in the International Journal of Qualitative Studies on Health and Well-being in 2020, interviewed girls averaging 14 years old in a rural district of Tamil Nadu, India, about what changed after their first period. The girls described being taught new codes of behaviour, including how to sit and how to keep distance from boys and men, restrictions on entering religious spaces and on cooking, requirements to cover up more, less freedom to move around unsupervised, and male relatives becoming noticeably more distant. Important caveat: this study interviewed just ten girls in one specific community. It does not describe your family, and it is not a claim about how any particular culture behaves. It is evidence that this experience exists and is documented, which matters when you feel like the only one.

Something broader supports the same feeling. Johnston-Robledo and Chrisler, in The Palgrave Handbook of Critical Menstruation Studies, summarise that across cultures girls' own accounts of their first period are dominated by secrecy and concealment, with negative feelings outweighing positive ones. Again: this is about how girls describe it, which is exactly what you are asking about.

And the finding from earlier is relevant here too. Marván and colleagues, in 2012, found that Mexican girls who had talked with their mothers about the emotional side beforehand were more likely to say they felt prepared. It was one survey in one country, and it shows a link rather than proof of cause, but the pattern points at the conversation about feelings rather than the diagram.

What to do about it

The most useful thing we can give you here is words. Pick whichever fits and say it as close to word for word as you like.

1. To open the conversation without triggering the whole ceremony: "I want to tell you something about my body, and I want to just tell you first, before we decide anything changes."
2. If you are worried about new rules landing all at once: "I know this means something in our family. Can we talk about what changes and can some of it wait? I am still getting used to it."
3. If you need practical things but not a conversation: "Can you get me pads next time you shop? I do not want to talk about it more than that right now."
4. If a change feels like too much: "I am not saying no. I am saying I need it to happen slower. Can we start with one thing?"
5. If the person you would naturally tell is the hardest one to tell: tell someone else first. An aunt, an older cousin, a school nurse, a teacher you like. Telling one adult is the goal. Which adult is up to you, and a written note or a message from the next room counts just as much as saying it.
6. To ask for something practical, like an app on your phone: name what it does, not what you want. "There is an app that tracks periods so I know when mine is coming. Can I show you it and then you decide?" Handing someone the decision makes them far more likely to say yes.

A worked example

Say you have had your period for two days and have not told anyone, because you are fairly sure that telling means a set of changes you are not ready for.

You start with the smallest true sentence, at a quiet moment rather than at dinner with everyone there: "I started my period on Tuesday. I did not want to make it a whole thing yet." Whatever the response, you have now done the hard part. If new expectations do come up, you have one more sentence ready: "Can we do one change at a time? I want to get used to this bit first."

Maybe they agree, maybe not about everything. Either way you have said it out loud, which is different from carrying it alone, and you did it in two sentences.

When it is more than feeling awkward

If the changes at home mean you are missing school, being kept away from people you need, or if anything makes you feel unsafe rather than just uncomfortable, that is bigger than a period conversation and you should not handle it alone. Tell a teacher, a school nurse, a counsellor, or another adult outside the situation. Being uncomfortable is normal. Being unsafe is not, and it is always worth telling someone.

I dreamed that my period started. Does that mean anything?

One girl asked what it means to dream about starting her period. It is a lovely question and the honest answer is more interesting than a yes or a no.

What is going on

Dreams are not messages sent to you. They are your own brain, running on its own material overnight. The material it uses is the stuff you have been thinking about and feeling. If your period is on your mind most days, it is genuinely unsurprising that it turns up while you are asleep.

What the research actually says

The idea that dreams draw on waking life is called the continuity hypothesis. Researchers describe dreaming as both continuous and discontinuous with waking life: your day turns up in your dreams, but rearranged rather than replayed.

The most recent large study of dream content is by Elce and colleagues, published in Communications Psychology in 2026. They collected 1,687 dream reports and 1,679 waking reports from 207 participants over a 15 day protocol and analysed them with language models. Stable traits, such as how much someone mind-wanders and how well they sleep, shaped dream content. In a second, separate group of 80 people who kept dream diaries during the 2020 COVID lockdown, dreams became more emotionally intense and referred more to being restricted, then drifted back towards normal over the following years. Together the authors read that as traits and lived experience both leaving fingerprints on dreams. Two caveats worth carrying: the participants were adults in Italy with an average age of about 35, not girls your age, and the authors state plainly that their analyses cannot establish cause and effect.

Now the part you actually asked about. There is a small amount of research linking where you are in your cycle to what your dreams are like, but it is weak, it rests on people remembering their own dreams, and it points in the opposite direction to your question: it is about dreams reflecting a cycle that is already happening. No study anywhere shows a dream predicting when a period will arrive, and none of that research can apply before your first period, because there is no cycle yet. Dreaming about it tells you about the last few weeks of your thoughts, not the next few weeks of your body. Nobody, including us and including the app, can tell you the date of your first period.

What to do about it

1. Read the dream as information about your week, not your future. The useful question is not "what does it mean" but "how much have I been thinking about this?"
2. If the answer is "constantly", that is worth doing something about. Waiting for something you cannot control is genuinely tiring.
3. Give the waiting a smaller place. Check the app once a week rather than every day. Constant checking feeds the loop.
4. Do the preparing instead of the waiting. Build a small kit and put it in your bag. Preparation is the part you control, and having done it lets your brain put the subject down.
5. Tell someone you are thinking about it a lot. Saying "I keep thinking about when my period will come" to a friend or an adult usually shrinks it. You will not be the only one thinking about it: girls' own accounts of the run-up to a first period are full of secrecy and of feeling unprepared, which is exactly the state that keeps a thought spinning.
6. If the dreams are frightening rather than just odd, or they are waking you up regularly, mention it to an adult. That is about sleep, not about periods.

A worked example

Say you dream your period started at school. You wake up and check. Nothing.

Instead of reading it as a sign, you notice something true: you have thought about this every day for a month. So you do three things. You put two pads and a spare pair of underwear in your school bag, so the scenario in the dream now has a plan attached. You decide you will look at the app on Sundays instead of every night. And you tell one friend that you keep thinking about it.

The dream may well come back. But the thing it was rehearsing is now something you are ready for, which is a much better outcome than an interpretation.

When it is more than a dream

Occasional vivid dreams are ordinary. If you are having distressing dreams most nights, waking repeatedly, or feeling anxious during the day about your period in a way that gets in the way of school or friends, tell a trusted adult. That is not being dramatic. Persistent worry is a thing adults can actually help with.

The bottom line

The thread running through this week is anticipation. Almost every question was really about a gap: the gap between knowing something is coming and knowing what to do when it does. Which product, what happens on day one, why your body is not doing the thing you were told to expect, what everyone will want from you afterwards, and what your own brain is doing with all that at night.

The good news is that gap closes with preparation, not with prediction.

• Products are a two-item list: catch it outside, or collect it inside. Start with a pad. Nothing gets lost inside you, and moving or hanging upside down does not change that.
• Cups are real and reasonable. In the four small studies that compared them head to head with pads and tampons, cups leaked about the same or slightly less, though the reviewers rated almost all of that evidence as low quality. Expect a slow start, and follow the wear times: a tampon out within 8 hours, a cup emptied at least every 12.
• On day one you need a pad, two spares, one adult told, and today's date written down. That is all.
• No cramps is not a fault. Pain typically begins six to twelve months after a first period as ovulation starts, so a quiet period is often just an early one.
• A long gap after your first period is normal. Ninety days with no period at all is the point to mention it, and so is a run of cycles that keep coming more than 45 days apart.
• If your period brings new expectations at home, you are allowed to ask for one change at a time. Say the small true sentence first.
• Dreams reflect what you have been thinking about. They do not predict dates, and nothing else does either.

If there is one gentle next step this week, make it the smallest one: log the days you actually notice something in the app, whether that is bleeding, an ache, or just feeling off. A few weeks of your own real data beats any prediction. And if any question here was really yours, tell one adult you trust. Not for permission, just so you are not the only person holding it.

Frequently Asked Questions

Can I use a tampon or a cup if I have never had sex?

Yes. Neither one requires you to have had sex, and using one does not change anything about that. What can make a first attempt uncomfortable is being tense, which tightens the muscles around the entrance. Going slowly, at home, with time and clean hands, is what makes it easier.

How often should I change a pad, a tampon or a cup?

A pad every three to four hours during the day, even if it looks almost clean, because changing is about freshness rather than how full it is. Overnight you can go longer with a pad or period underwear, which is why night versions exist. Internal products are different and stricter. A tampon should be changed every 4 to 8 hours and never left in for more than 8 hours, including overnight, because of a rare but serious infection called toxic shock syndrome. Never put a tampon in before bed and sleep through the whole night. A cup is emptied every 4 to 12 hours. If you get a sudden high fever, vomiting, diarrhoea, a rash or feel faint while using a tampon or a cup, take it out and tell an adult that same day.

Can I go swimming with a menstrual cup?

Yes. A cup collects blood inside your vagina, so it works in water the same way a tampon does. A pad does not work for swimming, because it soaks up pool or sea water. If you are new to cups, do not make a swimming day your first attempt.

Is it normal for my first few periods to be different lengths?

Yes, and it is expected. In the first year or two, cycles commonly run anywhere from about 20 to 45 days, and a period lasting three days one time and six the next is ordinary. It is the long-term pattern that matters, not any single cycle.

Do painkillers stop working if I use them every period?

There is no good evidence that pain relief taken for a few days a month stops working over time. But if something that used to help you stops helping, say that out loud rather than taking more, because it can mean the pain itself has changed. And the medicine and the amount are decisions for a parent, carer or doctor who knows your age and weight. Never decide those on your own, and tell an adult if you need something every single cycle.

Can stress or being busy actually delay my period?

Big changes such as illness, heavy training or significant stress can affect cycles, especially in the first years when things are not yet settled. If a cycle is late once, that is ordinary. If your period stops for 90 days after it had been coming, or your cycles keep arriving more than 45 days apart, that is the point to see a doctor.

What if I get my period and I am nowhere near a bathroom?

Folded toilet paper or tissue in your underwear will hold things for a while, and so will a folded jumper tied round your waist if you feel exposed. Then ask the nearest woman or girl you can find, including a teacher or school nurse. Almost every one of them has been in that exact situation and will simply hand you something.

Where this comes from

We only publish things we have checked in the original papers. Here is what this post is built on, and what each source actually found.

• van Eijk AM, Zulaika G, Lenchner M, et al., "Menstrual cup use, leakage, acceptability, safety, and availability: a systematic review and meta-analysis," The Lancet Public Health, 2019. Reviewed 43 studies covering 3,319 women and girls. Found cups hold 10 to 38 millilitres, are emptied every 4 to 12 hours, leak about the same as or less than pads and tampons, and are broadly safe, alongside a small number of serious adverse events. The authors rated the quality of the quantitative studies as low, with only two of moderate to high quality, so we have carried that caveat.
• McKenna KA & Fogleman CD, "Dysmenorrhea," American Family Physician, 2021;104(2):164-170. States that ordinary period pain begins on average six to twelve months after a first period, as ovulatory cycles begin, and that pain relief works best when started one to two days before bleeding. We deliberately do not publish the doses in this paper, because guideline doses are adult doses.
• De Sanctis V et al., "Primary Dysmenorrhea in Adolescents: Prevalence, Impact and Recent Knowledge," Pediatric Endocrinology Reviews, 2015. Reported period pain in anywhere from 16% to 93% of adolescents depending on the population and the question asked, with severe pain in 2% to 29%. The range is wide on purpose, and we have not collapsed it into a tidier number.
• Hillard PJA, "Menstruation in Adolescents: What's Normal?" Medscape Journal of Medicine, 2008;10(12):295. Sets out the ranges doctors use for teenagers: cycles of roughly 20 to 45 days in the early years, bleeding of 3 to 7 days, and 90 days as the evidence-based point at which a missing period should be evaluated.
• Gordon CM et al., "Functional Hypothalamic Amenorrhea: An Endocrine Society Clinical Practice Guideline," The Journal of Clinical Endocrinology and Metabolism, 2017;102(5):1413. Recommends evaluation for adolescents and women whose cycle interval persistently exceeds 45 days, or who have no period for three months or more, and notes that cycles typically do not exceed 45 days even in the first year after a first period. This is the source of the second threshold we give alongside the 90-day one.
• Carlson LJ & Shaw ND, "Development of Ovulatory Menstrual Cycles in Adolescent Girls," Journal of Pediatric and Adolescent Gynecology, 2019. Reviews how cycles mature after a first period. Reports that most early cycles happen without ovulation, while being explicit that studies disagree on the exact figures and that girls vary a great deal.
• Marván ML et al., "Mexican Adolescents' Experience of Menarche and Attitudes Toward Menstruation," Journal of Pediatric and Adolescent Gynecology, 2012. Surveyed 405 girls aged 12 to 15. Only 39% felt prepared for their first period, and those who had discussed the emotional side with their mothers beforehand were far more likely to feel prepared. Single-country sample, so we treat the exact figure with care.
• Gold-Watts A, Hovdenak M, Daniel M, Gandhimathi S, Sudha R & Bastien S, "A qualitative study of adolescent girls' experiences of menarche and menstruation in rural Tamil Nadu, India," International Journal of Qualitative Studies on Health and Well-being, 2020. Interviewed ten girls averaging 14 years old in one rural community, who described new behavioural rules, restrictions and changed family relationships after their first period. A very small, very specific sample, quoted here only as evidence that this experience is real and documented.
• Johnston-Robledo I & Chrisler JC, "The Menstrual Mark: Menstruation as Social Stigma," The Palgrave Handbook of Critical Menstruation Studies. Summarises that across cultures, girls' own accounts of their first period are dominated by secrecy and concealment, with negative feelings outweighing positive ones.
• Elce V et al., "Individual traits and experiences predict the content of dreams," Communications Psychology, 2026. Analysed 1,687 dream reports and 1,679 waking reports from 207 participants over 15 days. Found that personal traits and recent waking experiences together shape dream content. Participants were adults in Italy, not girls, and the authors state their analyses cannot establish cause and effect. The same paper describes dreaming as both continuous and discontinuous with waking life, so we have not presented it as a clean proof of the continuity idea.
• Ilias I, Economou NT, Lekkou A, Romigi A & Koukkou E, "Dream Recall and Content versus the Menstrual Cycle: A Cross-Sectional Study in Healthy Women," Medical Sciences, 2019;7(7):81. A questionnaire study of 944 women that found pleasant dream content associated with one phase of the cycle. This is the small, weak literature we refer to. It is self-reported and cross-sectional, it makes no predictive claim, and it cannot apply before a first period because there is no cycle yet.

None of this replaces a doctor. If something about your body worries you, or if anything here does not match what you are experiencing, tell a parent, carer or doctor. They can examine you and ask the questions an article cannot.
