Symptom guide
The cycle that stopped keeping its own schedule.
Irregular periods are usually the first sign of perimenopause — and also the symptom with the most important red flags. Both halves matter.
The short answer
Irregular periods in perimenopause happen because ovulation becomes inconsistent, making estrogen and progesterone production erratic. Cycles may shorten, lengthen, skip months, or vary in flow — all typical of the transition. However, very heavy bleeding, bleeding between periods, or any bleeding after 12 months without a period should be evaluated promptly.
What it can feel like
- Cycles arriving earlier or later than your lifelong pattern
- Skipped months followed by a return
- Flow noticeably heavier or lighter than your normal
- Shorter or longer periods
- New spotting patterns
Why cycles become irregular
Perimenopause begins when ovulation becomes inconsistent. Some cycles release an egg; others don’t. Without ovulation, progesterone isn’t produced in its usual rhythm, and estrogen swings without its counterweight — so cycle length, flow, and symptoms all become unpredictable. This can go on for several years before the final period.
Irregularity is usually the transition’s opening move, arriving before hot flashes for many women. Tracking your cycles — even roughly — gives a clinician some of the most useful information in your whole intake.
Bleeding patterns that need prompt evaluation
Some patterns deserve evaluation rather than reassurance: soaking through a pad or tampon hourly, bleeding lasting far longer than your normal, bleeding between periods, bleeding after sex, and — most importantly — any bleeding after 12 consecutive months without a period. These warrant timely in-person clinical review.
For typical perimenopausal irregularity alongside other transition symptoms, a structured review of your history helps confirm the picture and discuss appropriate next steps.

Common questions
How irregular is normal in perimenopause?
Considerable variation is typical — cycles shortening, lengthening, or skipping months. What matters is the change from your lifelong pattern and any red-flag bleeding.
What bleeding is a red flag?
Soaking through protection hourly, bleeding between periods, bleeding after sex, and any bleeding after 12 months without a period all warrant prompt in-person evaluation.
Can I still get pregnant with irregular periods?
Yes — ovulation is inconsistent, not absent, and pregnancy remains possible until menopause is confirmed (12 months without a period). Contraception is a conversation to have with your clinician.
How long does the irregular phase last?
Commonly four to eight years from the first cycle changes to the final period, though it varies widely between women.
How does Parée approach cycle changes?
Your intake captures your cycle story alongside symptoms and history. A licensed US clinician reviews it — including whether anything needs in-person evaluation first.
