Is irregular cycles a sign of perimenopause?

Periods arrive earlier or later than usual, or skip months entirely.

Why it happens

Irregular bleeding is one of the clearest clinical markers of the Early Menopausal Transition (STRAW+10 Stage -2). Progesterone begins declining before estrogen, creating an unopposed estrogen environment that leads to heavier or erratic periods.

Did you know? Less than 20% of U.S. primary care physicians have received formal menopause training — meaning this symptom is frequently misattributed to stress, anxiety, or ageing.

Don't guess.
Know your stage.

Our 5-minute Pattern Preview uses the Greene Climacteric Scale and STRAW+10 framework to show you where you are in your transition — and generate a report you can share with your doctor.

You are not alone

6,000 women enter menopause every day in the U.S., yet 1 in 3 receive an incorrect diagnosis first. Tracking irregular cycles helps build a clinical picture of your specific transition phase — evidence you can bring to any provider.
