What is perimenopause?

Menopause itself is when you haven’t had a period for 12 months (without hormonal contraception). It usually happens between 45 and 55, but it can be earlier.

What are the symptoms of perimenopause?

  • Periods becoming irregular.
  • Hot flushes and night sweats.
  • Trouble sleeping.
  • Mood changes, poor memory or brain fog.
  • Vaginal dryness, and more urine infections.
  • Headaches, joint aches, palpitations, and a lower sex drive.

Symptoms often last 7 to 9 years, sometimes longer. There’s no routine test; a doctor usually goes by your age and symptoms.

Can I still get pregnant during perimenopause?

The NHS advises keeping up contraception for 2 years after your last period if you’re 40 to 49, and for 1 year if you’re 50 or over.

When should I talk to a doctor about perimenopause?

Talk to a doctor about your options if symptoms bother you. Get checked if you start bleeding more rather than less, or if you bleed at all after 12 months without a period.
