Tracking timing, bleeding and symptoms can help you understand your usual pattern and describe changes clearly to a healthcare professional.
What to know
A menstrual cycle is counted from the first day of one period to the first day of the next. Cycle length and bleeding patterns can vary, especially during puberty, after pregnancy and around menopause.
Pain, mood changes and changes in bleeding can occur, but symptoms that disrupt daily life should not simply be dismissed as “normal”.
Key points
Track your patternRecord dates, bleeding and symptoms.
Notice bleeding changesWatch for very heavy, prolonged or between-period bleeding.
Pay attention to painSevere or worsening pain deserves assessment.
Review medicines and contraceptionSome treatments can affect bleeding patterns.
Signs and symptoms
Periods are one part of the wider menstrual cycle. Experiences differ, and the most useful comparison is often with your own usual pattern.
Bleeding
A period commonly lasts several days and may be lighter or heavier at different points. Track sudden changes, flooding or bleeding outside your expected period.
Cramps and body symptoms
Lower abdominal cramps, back pain, bloating, breast tenderness, headache and tiredness can occur around a period.
Mood and concentration
Hormonal changes may be associated with irritability, low mood, anxiety, food cravings or difficulty concentrating before bleeding begins.
Cycle irregularity
Cycles can be less predictable after periods first begin, after pregnancy, while breastfeeding and during the menopause transition. Persistent changes still deserve review.
Causes and contributing factors
Cycle timing reflects communication between the brain, ovaries and uterus. Many temporary and medical factors can alter that communication.
Hormonal life stagesPuberty, postpartum changes, breastfeeding and perimenopause can change cycle length or bleeding.
Pregnancy and contraceptionPregnancy is an important cause of a missed period. Hormonal contraception and intrauterine devices can also change bleeding patterns.
Health and lifestyle factorsStress, major weight change, intense exercise, undernutrition, thyroid disease and some medicines may affect cycles.
Gynaecological conditionsPCOS, fibroids, endometriosis, adenomyosis, infection and other conditions can cause pain or abnormal bleeding.
How healthcare professionals assess it
Assessment is individual. Not every person needs every test, and results must be interpreted alongside symptoms, history and examination findings.
History and tracking
A clinician may ask about cycle dates, bleeding amount, pain, pregnancy possibility, medicines, contraception and effects on daily life.
Examination
Depending on symptoms, an abdominal or pelvic examination may help identify tenderness, enlargement or another cause.
Tests
Pregnancy testing, a full blood count, thyroid or other hormone tests may be considered. Testing is guided by the pattern of symptoms.
Imaging or procedures
Ultrasound or other investigations may be recommended for persistent heavy bleeding, pain, suspected fibroids or other structural concerns.
Treatment and management
Treatment depends on the cause, severity, age, pregnancy plans and personal preferences. One plan does not suit everyone.
Pain relief
Heat and appropriate pain medicines may help cramps. Check suitability if you have stomach, kidney, bleeding or medication concerns.
Hormonal treatment
Some hormonal contraceptives can reduce pain, regulate bleeding or make periods lighter when medically suitable.
Heavy bleeding care
Treatment may include medicines that reduce bleeding and assessment for iron deficiency or anaemia.
Treat the cause
Thyroid disease, PCOS, fibroids, infection or other diagnosed conditions require condition-specific care.
Practical steps you can take
Track the first day of bleeding, duration, flow, clots, pain and related symptoms for several cycles.
Carry the menstrual products and pain plan that work for you; change or clean products as directed.
Note bleeding that soaks protection unusually quickly, wakes you repeatedly or limits normal activities.
Do not assume severe pain is normal simply because it happens every month.
If pregnancy is possible and a period is late, use an appropriate pregnancy test and seek advice when needed.
Questions to ask at an appointment
Writing questions down can make a consultation more useful, especially when symptoms are stressful or complex.
- Is my cycle pattern within an expected range for my age and circumstances?
- Could contraception, medicines or another health condition explain this change?
- Do I need a pregnancy test, blood count, hormone test or ultrasound?
- What options could reduce pain or heavy bleeding, and what are their side effects?
Common questions
Is a 28-day cycle required to be healthy?
No. Cycle length varies, and some variation can be normal. A persistent change from your usual pattern or symptoms that affect daily life is more important than matching one number.
Can stress delay a period?
Stress can affect the hormonal signals involved in ovulation and may delay a period, but pregnancy and medical causes should still be considered when appropriate.
When is bleeding considered urgent?
Seek urgent care for very heavy bleeding with faintness, breathing difficulty, chest pain, severe weakness, pregnancy possibility or severe pain.
When to speak with a healthcare professional
Arrange an assessment if symptoms concern you, affect daily life, persist, worsen or are different from what is normal for you.
