1. Your Periods Have Gone Completely Off-Script
If you're asking what are 7 signs of perimenopause, the answer starts with your cycle doing whatever it wants. Perimenopause is the transitional phase before menopause, when oestrogen and progesterone begin fluctuating unpredictably rather than declining in a straight line.
What most guides get wrong is framing this as a countdown to the end of something. It's more like your hormones have discovered improv comedy and you're the audience.
The classic signs of perimenopause include:
- Cycles that jump from 24 days to 45 and back again
- Heavier bleeding one month, barely anything the next
- Spotting between periods
- Periods that arrive with zero warning after years of clockwork
These fluctuations are normal and expected, not a sign something's gone wrong.
A common mistake is assuming irregular periods mean something serious. Usually they don't. But if bleeding becomes very heavy or persistent, that's worth a GP conversation.
2. Sleep That Ghosts You at 3am
Waking at 3am with your brain suddenly online is one of the most common signs of perimenopause. Falling progesterone affects sleep architecture, and many women find themselves wide awake in the small hours for no obvious reason.
The cruel part? You're exhausted all day, then wired the moment your head hits the pillow.
Some practical fixes that actually help:
- Keep the bedroom cool and dark, no negotiation
- Skip the wine wind-down, it fragments sleep later
- Get morning light within 30 minutes of waking
- Write the 3am thoughts down instead of rehearsing them
3. The Brain Fog Is Real: How to Manage Perimenopause Brain Fog
Learning how to manage perimenopause brain fog starts with accepting it's a genuine hormonal symptom, not a character flaw. Fluctuating oestrogen affects neurotransmitters involved in memory and focus.
You walk into a room and forget why. You lose the word "refrigerator." You put your keys in the freezer.
How to manage perimenopause brain fog in practice:
- Externalise everything: notes, alarms, one calendar
- Protect deep-focus time in the morning when oestrogen is higher
- Reduce multitasking, it makes the fog worse
- Move daily, even a brisk walk helps cognition
4. Your Skin Has Entered Its Second Puberty Era
Hormonal breakouts along the jaw and chin show up right alongside your first grey hairs. As oestrogen drops relative to androgens, oil glands get erratic and congestion returns to places you thought you'd left behind at 16.
At Dead Tired Club, we call this second puberty, and we built our range around it rather than pretending it isn't happening. The Got Bumps? Hormonal Acne BHA Serum uses salicylic acid to get inside the pore, not just sit on top of it.

Collagen loss is happening at the same time. The Got Lines? Copper Peptide Serum works on structure with GHK-Cu, a copper peptide studied for supporting collagen and elastin.

One honest limitation: no serum reverses hormonal skin changes overnight. Consistency over months is what moves the needle.
5. Mood Swings That Feel Like a Hostile Takeover
Rage at a supermarket self-checkout. Tears at an ad for insurance. Mood swings in perimenopause are driven by the same hormonal fluctuations affecting everything else, and they can feel completely out of proportion to the moment.
What helps:
- Name it in the moment ("this is hormonal, not me")
- Track patterns so you can predict rough days
- Move your body hard when the irritation builds
- Tell your people what's happening
The thing nobody tells you about perimenopause mood shifts is that they often ease once you stop fighting them and start expecting them.
6. Your Perimenopause Symptoms Checklist: What Else to Watch For
A perimenopause symptoms checklist helps you spot patterns before they feel overwhelming. Beyond the headline signs, watch for these:
- Joint aches and stiffness, especially in the morning
- Dry eyes, dry mouth, or changed skin texture
- Heart palpitations or a racing feeling
- Low libido or discomfort during sex
- Increased anxiety or a shorter fuse
- Hair thinning or changing texture
- Night sweats or hot flushes
- Vaginal dryness or urinary changes

Healthdirect's overview of menopause symptoms notes these vary widely in timing and intensity. Your list won't match your friend's, and that's normal.
7. When to See a GP for Perimenopause (And What to Say)
Knowing when to see a GP for perimenopause comes down to impact: if symptoms are disrupting your sleep, work, relationships, or mental health, that's your cue. You don't need to wait until things are unbearable.
What to say when you get there:
- Bring a written symptom log with dates
- Describe how symptoms affect daily life, not just that they exist
- Ask directly about hormonal and non-hormonal options
- Mention your family history of menopause timing
the Australasian Menopause Society's resources for women offers evidence-based information you can read before your appointment so you walk in prepared.
A common mistake is being brushed off and accepting it. If you feel dismissed, ask for a second opinion or a referral.

Frequently Asked Questions
At what age does perimenopause typically start?
Most women notice the first signs of perimenopause in their mid-to-late 40s, but it can begin as early as your mid-30s. The average age is around 45 to 47. Because the transition is gradual, many women dismiss early symptoms as stress or burnout. If you're in your late 30s or 40s and noticing changes to your periods, sleep, or mood, it's worth tracking what's happening rather than waiting for a specific age.
How long does perimenopause usually last?
Perimenopause can last anywhere from four to eight years, with some women experiencing symptoms for a decade. It ends 12 months after your final period, which marks menopause itself. The length varies significantly, and there's no way to predict your timeline. Tracking your symptoms over time gives you and your GP a clearer picture of where you are in the transition.
What is usually the first sign of perimenopause?
For many women, the first sign is a change in their menstrual cycle, whether that's shorter cycles, heavier bleeding, or periods that skip altogether. Others notice sleep disruption or mood shifts before any period changes. Because the signs of perimenopause vary so much between individuals, there's no universal first symptom. Pay attention to any pattern that feels new or unusual for you.
Can perimenopause cause sudden anxiety or mood swings?
Yes. Fluctuating oestrogen affects serotonin and other mood-regulating chemicals in the brain, which can trigger anxiety, irritability, or tearfulness that feels out of proportion to what's happening around you. Many women describe it as a hostile takeover of their personality. If mood changes are affecting your relationships or daily life, that's a conversation worth having with your GP rather than pushing through.
What should I do if I suspect I'm in perimenopause?
Start by tracking your symptoms for at least two to three months, noting period changes, sleep quality, mood, and anything else that feels different. Book an appointment with your GP and bring that record with you. Ask specifically about perimenopause and what options exist for managing your symptoms. You don't need to wait until things feel unbearable before seeking support.
