What changes are worth noting?
A cycle is counted from the first day of one period to the first day of the next. Record changes in the spacing, duration or heaviness of bleeding, along with pain or bleeding between periods. Your usual pattern and life stage help put a change in context.
You do not need a perfect record to seek help. A few dates and a description of the change are a useful starting point.
There can be several explanations
Pregnancy, hormonal contraception, stress, weight changes, thyroid problems and PCOS can affect periods. Other gynaecological conditions can also cause abnormal bleeding. A symptom alone cannot identify the cause.
Tell the doctor about new medicines, contraception and whether pregnancy is possible. Avoid starting hormonal treatment based only on an online checklist.
What might an assessment involve?
The doctor will review the bleeding pattern, other symptoms and medical history. Depending on these findings, a pregnancy test, blood tests, an examination or ultrasound may be considered. Each investigation should have a reason.
Bring previous reports and ask how a recommended test could change your care plan. Also mention tiredness or the effect of bleeding on work, study and sleep.
When to arrange care sooner
Bleeding after menopause, after intercourse or between periods deserves assessment. Heavy bleeding that affects daily life also warrants a discussion. Very heavy bleeding with dizziness, faintness, chest pain or breathlessness requires urgent medical attention.
Seek emergency care for these urgent symptoms instead of waiting for a routine appointment. For other concerns, describe the pattern when booking so that suitable timing can be discussed.
