Pathway · Menstrual changes
Periods that don't make sense anymore.
Cycle changes are usually the first sign of perimenopause, and the most confusing. Here's what's normal, what isn't, and what actually helps. If your cycle has been complicated for other reasons, endo, adenomyosis, premenstrual dysphoric disorder (PMDD), PCOS/PMOS, post-pill, a lot of the framing here still applies; the underlying drivers are different but the questions are the same.
Educational · not medical advice
Cycles can do almost anything in perimenopause: shorter, longer, heavier, lighter, gone for months, then suddenly back. The chaos is the hallmark. Most of it's normal, ovulation getting erratic, estrogen swinging without progesterone to balance it. But a handful of patterns deserve a doctor or specialist now, not later. Knowing the difference is most of the battle.
What's happening
What's actually going on
Ovulation becomes erratic. Estrogen and progesterone stop dancing in step.

What people actually find helps
Tracking is step one. Treatment options exist for almost everything else.

Doses, products, and routines vary person to person, run anything new past your doctor or pharmacist first, especially if you're on medication or in surgical or medically-induced menopause.
When to seek help
When to call the doctor
Most bleeding changes in perimenopause are normal. These specific patterns aren't 'wait and see'.
Heavy bleeding affecting your life
MedicalSoaking through protection hourly, planning your week around it, anemia symptoms (fatigue, breathlessness on stairs). It's treatable, get the appointment. Heavy clotty bleeding plus a heavy crampy uterus is the classic adenomyosis picture, and it's routinely written off as 'your age'.
Try a breathing practiceBleeding after sex
MedicalOften benign (cervical changes, GSM-related), but always needs a gynecological assessment to rule out cervical or endometrial issues.

MedicalEven one episode, even spotting, even after years. Always assess. Most causes are benign, but cancer needs ruling out.

MedicalPersistent irregular cycles, missed periods, or menopausal symptoms before 40 should be assessed for premature ovarian insufficiency (POI). Important for both fertility and long-term bone and heart health.

MedicalA useful threshold from Canadian gynaecologists: any period pain or bleeding that stops you doing daily life, work, school, sport or the things you enjoy isn't normal period pain, at any age. It warrants an endometriosis- and adenomyosis-aware referral, not a 'try the pill and come back'. Both are routinely missed for years; perimenopause is often when they finally get named.

More on this, when you want it.
The pattern matters more than any single bleed.
Cycle length and regularity over months
EvidenceNote start dates. A trend is more useful than a snapshot. A 7+ day variation in cycle length, persistent for three months, is an early perimenopause marker.
Bleeding heaviness, by what you're using
MedicalSoaking through a regular pad or tampon every hour for several hours, needing double protection, or passing clots bigger than a 2p coin all count as heavy. Worth a doctor or specialist.
How long bleeds last
MedicalBleeds longer than 7 days, or spotting between periods, are worth raising, usually benign in perimenopause but always worth checking.
Any bleeding after a year without one
MedicalOnce you've had 12 months with no period, any bleeding after that needs assessment. Most causes are benign. None is 'just menopause coming back'.
