Reasons many clinicians suggest an appointment

  • Periods stop for three months or more and you are not pregnant.
  • Cycles are regularly shorter than about 21 days or longer than about 35 days.
  • Bleeding is very heavy, for example soaking through a pad or tampon every hour for several hours, or passing large clots.
  • Severe pain that stops you doing normal activities.
  • Bleeding between periods or after sex.
  • Periods that suddenly change after years of regularity.
  • Bleeding after menopause.

Urgent help

Seek urgent care for very heavy bleeding with dizziness or fainting, severe abdominal pain, or any bleeding in pregnancy.

Make the appointment count

  • Bring three or more months of logged dates from your tracker.
  • Note flow level, pain, mood and other symptoms.
  • Write down medications, supplements and recent changes such as stress, weight change or travel.
  • Ask what tests are suggested and what to track next.

Frequently asked questions

Is an irregular period always a problem?

No. Many people have occasional variation. Persistent or sudden changes, severe pain or very heavy bleeding are worth discussing with a doctor.

What should I bring to the appointment?

Your logged dates for several months, flow and symptom notes, any medication and a list of questions.

Can a tracker diagnose PCOS or another condition?

No. It can show patterns that help a clinician, but only a clinician can diagnose.
