Early perimenopause: the stage most women miss
Early perimenopause is marked by a persistent change of seven days or more in your cycle length from one month to the next, while your periods still arrive. It is the stage most women miss — or get told they are "too young for" — because the first signs are usually subtle: disturbed sleep, low mood, foggy concentration and fatigue, not the hot flushes everyone expects. Over 45, it is diagnosed clinically from your pattern and symptoms, not from a single blood test.

What are the signs of early perimenopause?
- A change in cycle length of seven days or more. If the gap between your periods now varies by a week or more from one cycle to the next — a 27-day cycle followed by a 35-day one — you are here. That persistent seven-day-or-greater swing is the single cardinal marker in NICE NG23. Your periods still arrive; that is expected at this stage, not a reason to think nothing has begun.
- Early symptoms that are quiet, not dramatic. In a large cohort the most common perimenopause symptoms were fatigue and low energy (96%), memory problems (93%), poor concentration (91%), irritability (90%) and tension or nervousness (90%). Hot flushes rank lower than the cultural script suggests — which is exactly why this stage gets filed under stress.
- Age 40 to 47, sometimes earlier. The mid-thirties is possible. Under 40 with all of this needs a prompt, different conversation — see the note below.

Why is this the stage most women miss?
Because the loudest sign — the change in your cycle — is easy to shrug off, and the symptoms arrive dressed as ordinary life: a harder week at work, a bad run of sleep, a shorter fuse with the children. Too many appointments end with "you're too young for that" or "it's just stress." That is medical dismissal, not a clinical finding. The persistent seven-day cycle change is a recognised marker in its own right; you do not have to wait for skipped periods to be taken seriously. Walking in able to name your pattern in the language your gynaecologist uses carries far more weight than hoping the right questions get asked.
A note if you're under 40
If you are younger than 40 and everything here sounds like you, that is a different and more pressing conversation. It may be premature ovarian insufficiency — the ovaries winding down years ahead of schedule. It matters more, not less, because losing oestrogen this early carries real long-term risk to bones and heart. It is well understood and very treatable, but it calls for a gynaecologist soon rather than someday. Say the words "premature ovarian insufficiency" when you book. It is more common than the old figures suggested — around 1 in 27 women, not 1 in 100. See early menopause and POI in Malta.
How is early perimenopause diagnosed?
In a woman over 45 with typical symptoms, perimenopause is diagnosed clinically — from your menstrual pattern and symptoms — under NICE NG23. You do not need a blood test to confirm it, and a single FSH (follicle-stimulating hormone) reading cannot: it swings so widely at this stage that it can read 8 one Tuesday and 45 the next Friday. If a clinician offers to "confirm it with bloods," that one test can't — your cycle log can. The bloods that do matter are a different set, ordered to rule out look-alikes like thyroid problems, low iron and low vitamin D — see blood tests in Malta.
Is it just stress — or is it hormones?
The instinctive explanation is stress, and the trap is that stress is real too. But the biology here is specific and worth knowing: in early perimenopause your oestrogen is not running out — it is becoming erratic, swinging high then low from month to month instead of holding the steady rhythm it kept for thirty years. That instability is what reaches your mood, your sleep and your concentration. Rest doesn't fix a hormonal swing. When the cycle change and the symptoms arrive together, the pattern points to the transition — not to a character that has quietly changed.
How this shows up in Malta
Malta makes this stage easier to miss, not harder to have. There is no dedicated public menopause clinic at Mater Dei Hospital or Gozo General; the public route is a GP referral into general gynaecology outpatients, where an early, subtle presentation is easily lost. One Maltese gynaecologist running a menopause session reported seeing roughly two menopause patients a year, mostly expatriates — not because Maltese women aren't in perimenopause, but because a Catholic-conservative culture of intergenerational silence keeps them from naming it. And when treatment is discussed, HRT is private-pay in Malta — the visit may be free, the medicine is not. In that quiet, the woman who arrives with a tracked cycle and the right vocabulary is far harder to wave away.
