What Stage of Perimenopause Am I In?

Built on STRAW+10, the international staging system menopause clinicians use to place you in late reproductive, early perimenopause, late perimenopause or postmenopause.

Question 1 of 5

What are your cycles like in the last 12 months?

Question 2 of 5

When was your last period?

Question 3 of 5

Hot flushes or night sweats?

Question 4 of 5

How old are you?

Question 5 of 5

Vaginal dryness or painful sex?

The four stages, explained

STRAW+10 (Stages of Reproductive Aging Workshop, 2011 update) is the gold standard clinicians use. It puts cycle pattern at the center because hormones swing too much for blood tests to reliably stage you under 45.

Late Reproductive Stage

  • Cycles still regular but subtly shorter
  • Possible early symptoms: PMS worsening, sleep changes
  • Fertility declining but possible

Early Perimenopause

  • Cycle length varies by 7+ days from your usual
  • Hot flushes and night sweats can begin
  • Mood, sleep and brain fog often start here

Late Perimenopause

  • Skipped periods of 60+ days
  • Hot flushes and sleep disruption usually peak here
  • Final period typically within 1–3 years

Postmenopause

  • 12+ months since your last period
  • Vasomotor symptoms gradually ease for most women
  • Bone, heart and vaginal tissue need ongoing attention
