The Perimenopause Stage Checklist: Which Phase Are You Actually In
Your menstrual cycle, not your symptom count, tells you which stage of perimenopause you are in. Cycle lengths that keep varying by seven days or more point to early perimenopause, and 60 or more days between periods points to late. Grace Family Acupuncture and Holistic Medicine in Overland Park, Kansas, offers this perimenopause symptoms checklist to help you find yours.
Your symptoms are real, and this checklist records them alongside the cycle pattern that sets your stage.
The perimenopause symptoms checklist
Use it in three steps:
Track your cycle start dates for a few months.
Check Parts B and C for the last twelve months, and use your cycle dates for Part A.
Read the results below, then take your completed list to an appointment.
This is a self-observation aid, not a diagnosis, and Part A assumes natural periods: it does not apply if you use hormonal birth control or a hormonal IUD, have had a hysterectomy or endometrial ablation, have polycystic ovary syndrome, or are in or after cancer treatment.
Part A: Stage markers (your cycle decides your stage)
Before perimenopause
My periods are still regular, but my cycles have become shorter.
Early perimenopause
My cycle length varies by seven days or more from one cycle to the next.
That variation has happened more than once in the last ten cycles or so.
Late perimenopause
have gone 60 days or more without a period.
Postmenopause
I have gone 12 months in a row without a period.
Part B: Full list of perimenopause symptoms that support the picture (they occur at any stage)
Temperature and sleep
Hot flashes or night sweats, covered in our guide to hot flashes and night sweats
Trouble falling asleep, or waking in the night
Tiredness that rest does not fix, covered in our guide to perimenopause fatigue and sleep
Mood and thinking
Irritability, anxiety, or low mood, covered in our guide to perimenopause anxiety and mood changes
Brain fog or trouble concentrating
Bleeding
My flow has become lighter than it used to be.
My flow has become heavier than it used to be (very heavy bleeding is covered in the red flags below).
Body
New aching or stiff joints, covered in our guide to menopause-related joint pain
Vaginal dryness or discomfort during sex
Bladder changes, such as needing to urinate more often
Part C: Patterns a Chinese medicine practitioner listens for (a traditional framework, not a diagnosis)
Heat and dryness
Night sweats, evening warmth, a dry mouth, or waking in the night
Energy and digestion
Tiredness that deepens after meals, with foggy thinking
Tension
Irritability, tight shoulders, or a short fuse
Mind at bedtime
A racing mind when you try to sleep
What your answers suggest
Start with Part A. Cycles in perimenopause are unpredictable, so judge by the pattern across several months, not by one cycle. The highest stage that has a checked cycle marker is your best estimate of your stage: a 60-day gap suggests late perimenopause, repeated cycle variation suggests early perimenopause, and 12 months without a period means postmenopause.
More checks in Part B do not mean a later stage. If you checked many symptoms but your cycles are still regular, perimenopause cannot be confirmed from symptoms alone, so raise the pattern with your physician.
Part C works differently, because Chinese medicine reads symptoms as patterns. Heat and dryness point toward depletion of Kidney yin, tiredness after meals with foggy thinking toward a weakened Spleen, irritability and tight shoulders toward Liver qi stagnation, and a racing mind at bedtime toward the Heart and Kidney failing to communicate. These are traditional labels for patterns of symptoms, not organ diseases. Several overlap with Part B because Part C groups the same symptoms the way a practitioner does. Many women show more than one pattern, and these four are examples, not a complete list. Tongue and pulse assessment helps a practitioner tell which pattern leads.
The four stages, and what changes in each
Researchers who study the menopause transition use a staging system called STRAW+10. It puts cycle pattern first and treats symptoms as supporting information only. Your symptoms still matter, since they are what you and your practitioner work with.
Before perimenopause: the late reproductive years
Cycles are still regular, but subtle changes can begin, most often cycles getting shorter. Some women feel no different yet, and others notice sleep or mood changes.
Early perimenopause
The length of your cycles starts to vary: the gap between one cycle and the next differs by seven days or more, and the pattern repeats within about ten cycles. Flow may turn lighter or heavier, and pregnancy is still possible.
Late perimenopause
You begin to skip periods, with 60 days or more between them. Hormone levels swing widely, hot flashes and night sweats become more likely, and the stage lasts one to three years on average. You may see a middle phase described elsewhere, but the formal staging system has two transition stages, early and late.
Postmenopause
Menopause is confirmed once you have gone 12 months in a row without a period, and postmenopause is the time after that. Hot flashes and night sweats are most likely in the first couple of years after your final period, and vaginal and urinary symptoms become more common over time.
Age is not part of the staging. Perimenopause often begins in the 40s and can begin in the 30s. It can last two to eight years, with an average of about four. The average age of menopause is 51. Periods that stop before 40 need a medical assessment.
This cycle-based method assumes natural periods. It cannot stage you if you use hormonal birth control or a hormonal IUD, have had a hysterectomy or endometrial ablation, have polycystic ovary syndrome, or are in or after cancer treatment. A physician can use other markers in those cases.
What is not perimenopause, and needs a doctor
Irregular periods are common in perimenopause, but see your physician promptly for any of these:
Any bleeding after 12 months without a period
Bleeding between periods or after sex
Very heavy bleeding, or bleeding that lasts longer than seven days
Periods less than 21 days apart
Periods that stop before age 40
Weight loss you did not intend
Soaking through a pad or tampon every hour for more than two hours in a row, or heavy bleeding with dizziness, weakness, or shortness of breath, needs prompt medical attention.
What to do with your completed checklist
If anything in the red flag list applies to you, bring the checklist to your physician first, along with your cycle dates. Otherwise, bring it to any appointment where you want to discuss your cycle and symptoms. At Grace Family Acupuncture and Holistic Medicine in Overland Park, the first visit is a full intake covering symptoms, menstrual history, sleep, digestion, temperature patterns, and stress, with tongue and pulse assessment, so a completed checklist, Part C included, gives you ready answers. Every session is exactly 60 minutes, and the practice has served Overland Park since 2002.

FAQ
-
Symptoms can start while periods are still fairly regular, which makes them easy to miss. Hot flashes are not always the first sign: shorter cycles, sleep changes, and mood shifts can come earlier.
-
Perimenopause can last two to eight years, with an average of about four. Hot flashes and night sweats are most likely in late perimenopause and the first couple of years after your final period.
-
Changing cycle lengths, skipped periods, lighter or heavier flow, hot flashes, sleep problems, mood changes, and vaginal dryness.
-
Cycle variation, hot flashes, and sleep disruption are common at 45, but your cycle, not your age, sets your stage.
-
Late perimenopause starts when you go 60 days or more without a period, and it lasts one to three years on average. Hot flashes and night sweats become more likely.
-
Yes. Estrogen rises and falls unevenly, so symptoms vary in strength and timing, and cycle lengths change too.
-
A missed period can come from either, and perimenopause does not rule out pregnancy while you still have periods. Take a pregnancy test if there is any chance.
-
Most often in the 40s. They can start in the 30s, or not until the 50s.
