You’re Not Imagining It: 10 Symptoms of Perimenopause That Often Get Missed
If you’ve been thinking:
“This doesn’t feel like me.”
“I’m sure something’s changed.”
“Maybe I’m just not coping very well.”
I want to say this clearly: You’re not imagining it.
Perimenopause can begin years before menopause itself, and the symptoms aren’t always the obvious ones people talk about.
Hot flushes might come later… Irregular periods might not be the first sign.
Instead, it often starts with subtle shifts that are easy to dismiss… especially if you’re busy, and used to holding everything together.
What is perimenopause again?
Perimenopause is the stage leading up to menopause, when oestrogen and progesterone begin to fluctuate.
It can start in your 40s… sometimes earlier.
Hormones don’t decline smoothly at first. They fluctuate. And those fluctuations can affect your brain, nervous system, sleep, metabolism and stress response long before periods stop.
That’s why symptoms can feel confusing and disconnected.
10 symptoms of perimenopause that often get missed
Not every woman will experience all of these.. but many will recognise several.
1. Anxiety that feels new or amplified
You may feel on edge, restless, or more prone to racing thoughts… even if you’ve never struggled with anxiety before.
2. Waking in the early hours (3–4am)
Falling asleep might be easy. Staying asleep is not.
3. Brain fog
Forgetting words. Losing focus mid-sentence. Feeling less mentally sharp.
4. Sudden dips in confidence
Second-guessing yourself more than you used to.
5. Feeling overwhelmed by things you used to manage easily
Your stress tolerance feels lower.. not because you’re weaker, but because your buffering system has shifted.
6. Heavier, closer-together or slightly unpredictable periods
Even subtle cycle changes can be early signs.
7. More intense PMS
Mood swings, irritability, breast tenderness or headaches may worsen.
8. Fatigue that doesn’t improve with rest
You sleep but still wake tired.
9. Changes in weight distribution
Particularly around the middle, even if your habits haven’t dramatically changed.
10. A persistent feeling of “not quite myself”
This is the one women struggle to explain and the one that matters most.
Why these symptoms are often dismissed
Perimenopause tends to overlap with:
busy careers
teenagers or young adult children
caring for ageing parents
relationship shifts
general midlife pressure
So it’s very easy to attribute everything to stress.
And stress is often part of the picture.
But hormonal fluctuations affect:
serotonin (mood regulation)
cortisol (stress response)
blood sugar balance
sleep cycles
energy production
So your body may now be responding to normal life stress in a completely different way.
That’s physiology… not failure.
Blood tests don’t always give clear answers
Many women are told their hormone levels are “normal”.
But in early perimenopause, hormones fluctuate. A single blood test can’t always capture that shift.
This can leave women feeling dismissed or doubting themselves.
If your symptoms are real, they deserve to be taken seriously… even if test results look reassuring.
What recognising this stage allows you to do
When women understand that perimenopause may be contributing:
self-blame softens
extreme dieting often stops
pushing through becomes less automatic
nourishment becomes more intentional
stress is treated as physical, not just emotional
And that shift alone can make things feel steadier.
Gentle first steps
You don’t need dramatic changes.
Start with:
Regular, balanced meals to support blood sugar
Adequate protein intake
Consistent sleep routines
Reducing unnecessary pressure where possible
Listening to your body instead of fighting it
Perimenopause responds well to steadiness, not extremes.
A final word
If something feels different, trust that instinct.
Perimenopause doesn’t always shout.
It often whispers.
And recognising it isn’t about labelling yourself — it’s about understanding your body well enough to support it properly.
You’re not imagining it.
And you’re certainly not alone.
