I still have periods. Can it be perimenopause?
Yes — that is exactly what perimenopause is. Periods continuing is why the connection so often is not made, and why women are treated for anxiety or insomnia for two years first.
My blood test was normal. Does that rule it out?
No. Hormones fluctuate erratically through the transition, so one sample can look entirely normal in someone with unmistakable symptoms.
Your symptoms are the diagnosis. A normal FSH should not be used to refuse you treatment.
Can I start HRT before my periods stop?
Yes. You do not have to wait, and waiting has no clinical advantage.
You will still need contraception, since HRT does not provide it.
Why is my anxiety suddenly so much worse?
Falling and fluctuating oestrogen affects mood regulation directly, and anxiety arriving in your forties without an obvious cause is a common presentation.
It is frequently treated as primary anxiety — which is worth questioning if it started alongside cycle changes or worsens premenstrually.
Could this be my thyroid?
Possibly, and it should be checked. An underactive thyroid produces near-identical symptoms and is treated entirely differently.
Iron deficiency does the same, and heavy perimenopausal periods are a common cause of it.
How long does perimenopause last?
Commonly four to eight years. That is long enough that "waiting it out" is not a neutral choice.
Is it too early for me at 42?
No. Perimenopause commonly begins in the mid-forties and can start in the late thirties.
Under 45 is worth investigating properly rather than dismissing, because early menopause is managed differently.
What is the single most useful thing I can bring to an appointment?
A three-month symptom and cycle diary. It converts "I have not felt right" into a pattern, and a pattern is considerably harder to dismiss.
