When bleeding changes need medical attention

A clear safety guide for changes that should not be dismissed as ‘just hormones’.

In brief

In brief

Periods can become irregular, lighter or heavier during perimenopause. That does not make every bleeding change automatically harmless. After 12 months without a period, any vaginal bleeding should be checked—even once, even a small amount, and even without pain. Most causes are not cancer, but early assessment matters.

  • Arrange medical advice for any bleeding after menopause, bleeding after sex, or persistent bleeding between periods.
  • Discuss periods that are much heavier, last much longer, happen very close together or are affecting daily life.
  • If using systemic HRT, ask what bleeding is expected for your regimen and contact your clinician promptly when it continues outside the expected starting or dose-change window.
  • Record timing, amount, clots, pain, dizziness, pregnancy possibility, medicines and whether bleeding follows sex.
  • Do not stop prescribed treatment solely from app information; contact the prescriber for individual advice.
