Period cramps can be common, especially near the beginning of a period. However, pain that is severe, becoming worse or repeatedly affecting school, sleep, movement and everyday activities deserves medical attention. This EVA self-check can help you understand and describe your pain pattern, but it cannot diagnose the cause.
Mild or moderate cramps can happen before or during a period as the uterus contracts to release its lining. However, pain that is severe, worsening, unusual or repeatedly interrupts school, sleep and everyday activities deserves medical attention. Other symptoms occurring with the pain can also help show when faster support is needed.
Hormonal changes during puberty can increase the amount of oil produced by the skin, making acne more likely. Some people also notice predictable breakouts around their period. However, one pimple, its location or its timing cannot confirm a hormonal condition. Tracking the pattern and speaking with a healthcare professional can help when acne is persistent, painful or accompanied by other hormonal signs.
Iron helps your body make haemoglobin, a protein in red blood cells that carries oxygen around your body. During the teenage years, your body needs more iron because you are growing, and menstrual periods increase iron loss. Low iron can sometimes lead to iron deficiency or iron-deficiency anaemia, making you feel unusually tired or weak. Only a healthcare professional can diagnose low iron with the right assessment and, when needed, blood tests.
Polycystic ovary syndrome, usually called PCOS, is a hormonal condition that can affect menstrual cycles, ovulation, skin, hair and the way the body responds to insulin. People with PCOS can experience very different symptoms, and having PCOS does not mean that every symptom will appear. Despite its name, a person does not need to have ovarian cysts to have PCOS.
A period does not need to arrive on the same calendar date every month. Teenage cycles can naturally vary, especially during the first few years after periods begin. Learn how to count your cycle correctly, what timing can be common during adolescence and when a long gap between periods should be checked.
Feeling more irritable, tearful, anxious or sensitive before a period can be part of premenstrual syndrome, or PMS. These feelings are real and may be connected to changing hormone levels during the menstrual cycle. Learn how to recognise a premenstrual pattern without blaming every emotion on your period.
Periods naturally vary, but bleeding may be considered heavy when it lasts longer than seven days, requires very frequent period-product changes, causes repeated leaks or interferes with everyday activities. Heavy menstrual bleeding can also contribute to iron-deficiency anaemia. This EVA self-check helps you notice and describe your flow pattern, but it cannot diagnose the cause.
Heavy menstrual bleeding means losing enough blood during a period that it affects daily life or may cause health problems. Signs can include soaking through period products very quickly, needing double protection, waking at night to change products or bleeding for more than seven days. Heavy bleeding can sometimes lead to iron-deficiency anaemia and may occasionally be linked with a bleeding disorder.
Heavy periods can cause the body to lose iron faster than it can replace it. Over time, iron stores may become low and iron-deficiency anaemia can develop. This may cause unusual tiredness, weakness, headaches, dizziness, shortness of breath or difficulty concentrating. A healthcare professional can assess the bleeding, arrange blood periods.
Yes. PCOS can begin during the teenage years, but diagnosing it in adolescents is more challenging than in adults because many normal puberty changes such as irregular periods and acne can look similar to PCOS. Doctors usually look for symptoms that continue over time rather than making a diagnosis based on one sign alone.
Headaches are common during the teenage years and may feel like pressure, tightness, heaviness, pulsing or throbbing pain. Possible triggers include dehydration, missed meals, stress, poor sleep and long screen or study sessions. Migraine is a specific neurological condition that may cause stronger headaches together with nausea, vomiting, visual changes or sensitivity to light and sound. Recognising your pattern can help you understand common triggers and know when medical attention is needed.
Ovulation is the part of the menstrual cycle when an ovary releases an egg into a fallopian tube. It usually happens once during an ovulatory cycle, but its timing varies and it is not always on day 14. Hormones coordinate the process, and changes in discharge or mild lower-abdominal discomfort may sometimes happen around this time. Ovulation also creates the part of the cycle when pregnancy can occur if sperm fertilises the egg.
Clear or white vaginal discharge is usually a normal part of puberty and vaginal health. Its amount and texture may change during the menstrual cycle, and it may dry slightly yellowish on underwear after being exposed to air. Learn what healthy discharge commonly looks like and which changes deserve medical advice.
Periods may arrive early, late or with a different flow during the first few years after they begin. This often happens because the hormone system controlling the menstrual cycle is still developing. Learn which changes can be common, what else can affect cycle timing and when irregular periods should be checked.
PMS can cause emotional and physical symptoms before a period, but symptoms that are very intense, disrupt everyday life or continue throughout the month may need extra attention. Learn how timing, severity and repeated patterns can help you understand when it is time to ask for professional support.
Small jelly-like clots can sometimes appear during a period, especially when the flow is heavier. Learn what period clots are, which clot patterns can be common and when frequent or unusually large clots may be a sign of heavy bleeding that should be checked.
PCOS is a hormonal condition that can be linked with irregular or infrequent periods, persistent acne, increased facial or body hair and scalp-hair thinning. Symptoms vary, and having one of these changes does not mean that you have PCOS. Diagnosis during adolescence can be especially complex because normal puberty can cause similar changes. This EVA self-check helps you notice the overall pattern, but it cannot diagnose PCOS.
Fine facial and body hair is normal, and its colour and amount naturally differ between people. However, new or increasing thick, dark hair on areas such as the upper lip, chin, chest or abdomen may sometimes be influenced by androgen hormones. This pattern is called hirsutism. It can occur with PCOS or other conditions, but facial hair alone cannot confirm a hormonal problem.
PCOS can affect different people in different ways. Some teenagers may have irregular periods, while others notice persistent acne, increased facial or body hair, thinning scalp hair or weight changes. Having one of these signs does not automatically mean you have PCOS, because many other conditions and normal puberty changes can cause similar symptoms. Doctors look at the overall pattern rather than one symptom alone.
Bloating can make your abdomen feel unusually full, tight or stretched, and it may temporarily look more swollen. It can happen before a period, but gas, constipation and digestive conditions may cause similar symptoms. Tracking when bloating appears and what happens alongside it can help you understand whether it follows your menstrual cycle or another pattern.
Hormones are chemical messengers that travel through the body and help coordinate puberty, growth, ovulation and the menstrual cycle. Changing hormone levels may also influence skin, body hair, sweat, breast tenderness, energy and emotions. However, hormones do not explain every feeling or symptom, and different people can respond to the same hormonal changes in very different ways.
A small amount of facial hair can be a normal part of puberty. Hormones called androgens can make hair on the upper lip, sideburn area or chin more noticeable, and genetics also play a big role in how much hair someone has. Learn what is commonly normal, when hair growth may be linked to hormones such as PCOS and when it is worth getting checked.
Yes, ongoing or intense stress can sometimes make a period arrive later than expected or cause an irregular cycle. However, stress is only one possible explanation. Learn how stress may affect cycle signals, what you can do to support yourself and when a delayed period should be checked.
A few small marks of blood can be difficult to identify. Is your period beginning, ending or is it spotting between periods? Learn how timing, amount and your overall bleeding pattern can help you understand the difference—and when unexpected spotting should be checked.
Day 1 is the first day of your menstrual cycle. Learn how to identify it, why it matters for tracking your cycle, and what you can expect when your period begins.
No. Weight gain is a possible PCOS symptom, but it does not happen to everyone. People with PCOS can have many different body shapes and sizes, and someone can have PCOS while remaining within their usual weight range. Body size alone cannot confirm or rule out PCOS.
Stomach pain is one of the most common symptoms during childhood and the teenage years. It may be caused by gas, constipation, indigestion, menstrual cramps, viral infections, urinary problems or many other conditions. Most stomach aches improve on their own, but severe, persistent or worsening pain especially with vomiting, fever, bleeding or fainting should always be medically assessed.
You do not need to know whether a body change is “serious” before asking for help. Speak with a healthcare professional when a puberty change begins unusually early or late, a symptom persists or worsens, periods become difficult to manage, or discomfort interferes with school, sleep or everyday activities. You can also book a visit simply because you have a question or need reassurance. An adolescent reproductive-health appointment often begins with conversation and education rather than an internal examination.
Before a period, you may suddenly want chocolate, chips, sweets or comfort food more than usual. These cravings are common and can be linked to hormone changes, appetite shifts, energy needs and emotions. Learn why cravings happen, how to respond without guilt and when eating changes may need extra support.
Period flow can be light, moderate or heavy, and it may change from one day to another. Instead of trying to measure the exact amount of blood, learn the everyday signs of heavy bleeding—such as changing products very frequently, bleeding for more than seven days or having your period interfere with school, sleep and daily life.
Think your period has to come every 28 days? Not necessarily. Learn what a menstrual cycle actually is, why cycle lengths can vary, and why your own pattern matters more than a perfect number.
There is no single test that can diagnose PCOS. Healthcare professionals combine your medical history, menstrual pattern, symptoms, physical examination and, when needed, blood tests or an ultrasound. In teenagers, diagnosis is especially careful because many normal puberty changes can look similar to PCOS. Doctors also rule out other conditions that can cause similar symptoms before confirming the diagnosis.
Vaginal discharge is a normal mixture of moisture, cervical mucus, microorganisms and cells naturally shed from the vaginal lining. Fluid from the vaginal walls helps keep the vagina moist, while the cervix produces mucus that changes during the menstrual cycle. These secretions travel through the vagina and leave through the vaginal opening.
Periods are a normal biological process, but myths, teasing and silence can make them feel embarrassing. Learning to use clear language, ask for what you need and choose trusted people to speak with can make period care easier. You decide what information feels private and how much you want to share.
PCOS stands for polycystic ovary syndrome. It is a hormone condition that can affect ovulation, which may lead to irregular periods or missed periods. Some people with PCOS may also notice acne, extra facial or body hair or changes in weight—but not everyone has the same symptoms. Learn what PCOS can look like, why it can affect your cycle and when it is worth getting checked.
Headaches can sometimes appear before or during a period. Some may feel mild and pressure-like, while others may be migraine attacks with throbbing pain, nausea or sensitivity to light and sound. Learn how cycle changes may affect headaches, what can help and which symptoms need medical attention.
Your period may be lighter, heavier, shorter or longer than it was last month. Some variation is common, especially during the teenage years when cycles may still be settling. Learn what can influence your flow, how to track changes and when a new pattern deserves medical attention.
