Irregular periods, heavy bleeding and period pain

What symptoms and history should I describe?

Count cycle length from the first day of one period to the first day of the next, rather than comparing calendar dates. Record how many days you bleed, the heaviest days, clots and spotting. Note whether the change is new or has been present since the first periods.

Heavy flow can show up as frequent product changes, leaks, prolonged bleeding or disruption to work, school and sleep. Pain that repeatedly stops normal activity also deserves a conversation. These experiences matter even when an app says that a cycle is normal.

How is the problem assessed?

Bring a simple timeline rather than trying to choose a diagnosis beforehand. A clinician may consider pregnancy, medicines, thyroid problems, PCOS or a gynaecological cause according to the history and examination. Not every patient needs ultrasound or every hormone test.

For heavy bleeding, the doctor may discuss a blood count or other investigations. Tell them about tiredness, breathlessness, easy bruising and medicines that affect bleeding. If an examination is suggested, ask what it involves and how your consent and privacy will be respected.

What treatment and follow-up might be discussed?

Treatment depends on the cause and the goal: reducing pain, reducing bleeding, managing an underlying illness or investigating fertility concerns. Medicines and hormonal options are selected according to the patient’s circumstances and contraindications. Do not take someone else’s period-regulating prescription.

Pain or bleeding that does not settle with initial care may need specialist assessment. New bleeding after sex or between periods should be mentioned explicitly. A menopause-related explanation should not be assumed for every new bleeding pattern.

Before leaving, ask what changes to track, how long the proposed plan will be tried and when to return. Keep the dates of any test and the exact prescription with your cycle record so follow-up can assess change instead of restarting the history.

Questions to ask at the appointment

• Which part of my bleeding pattern needs investigation?
• Do pregnancy testing, a blood count or thyroid testing fit this history?
• What options are suitable for pain or heavy bleeding in my case?
• When would a gynaecologist’s assessment be needed?

Take a short written list and begin with your most important concern. If a test or treatment is recommended, ask what decision it will help make and how the result will be communicated. Bring the plan back at follow-up so you can discuss what improved and what remains unresolved.
