Irregular periods describe a pattern, not a single diagnosis. Recording what has changed helps a clinician distinguish variation around puberty or perimenopause from a problem needing assessment.
Keep a simple record
Note the first day of each period, how long bleeding lasts and whether there is spotting between periods. Record pain, unusually heavy flow and medicines or contraception. A calendar is enough; an app is optional. Bring several months of information if available, but do not delay seeking care to complete a perfect record.
Consider the wider context
Pregnancy, hormonal contraception, changes in weight, stress, thyroid problems and conditions affecting ovulation can all be relevant. Tell the clinician about major changes in health, exercise or eating. A missed period should not automatically be attributed to stress or PCOS when pregnancy is possible.
Ask what needs investigation
The history helps decide whether examination, a pregnancy test, blood tests or an ultrasound is appropriate. Not everyone needs every hormone test. Ask which explanation is being considered and what each investigation would add. If pregnancy is a goal, mention that early because it affects the discussion.
Know when to seek help sooner
Bleeding between periods, after sex or after menopause needs assessment. Heavy bleeding with faintness or severe pain warrants urgent care. A missed period together with unusual bleeding and abdominal pain also needs prompt assessment. At follow-up, ask what pattern to watch for, whether treatment is intended to regulate bleeding or address a specific cause, and when persistent irregularity should be reviewed again.
