Perimenopause Cycle Changes: What's Normal and What's Not
Last reviewed July 10, 2026 by the Dot editorial team · Sources cited below
Cycle changes are usually the first sign of perimenopause. Cycles can shorten, lengthen, skip, or vary in flow — sometimes wildly — for years before periods stop. This is expected. But some bleeding patterns always warrant a licensed healthcare provider: soaking a pad every hour, cycles under 21 days, bleeding between periods, or bleeding after 12 period-free months.
What's expected in the transition
Early perimenopause often shortens cycles as the follicular phase compresses. Later perimenopause brings longer skips punctuated by heavier or clottier bleeds. This reflects less regular ovulation and estrogen surging without balancing progesterone.
Average perimenopause duration is about 4 years, with wide individual variation.
What to track
- Start and end dates of every period
- Pads/tampons per day and largest clot
- Any spotting between periods or after intercourse
- Any bleeding after a month or more with no period
