Perimenopause doesn’t always make a dramatic entrance. For some women, the first clue is a shift in their periods — arriving earlier, later, or heavier than usual. For others, it is disturbed sleep, mood changes they can’t quite explain, or just a vague sense that their body is behaving differently than it used to.
If any of that sounds familiar, you are not imagining it — and you don’t need to wait until things get worse before talking to someone.
At Shire Family Medical, perimenopause is approached as part of broader, ongoing women’s health care. A GP can help you work out whether what you’re experiencing is related to hormonal change, whether other causes should be considered, and what options might suit your health history and preferences.
This article walks through common perimenopause symptoms, when it’s worth booking an appointment, and what to expect from a GP conversation — even if you’re not sure yet whether you’re “in menopause.”
What Is Perimenopause?
Perimenopause is the transition leading up to menopause. Menopause itself is defined as 12 consecutive months without a period. Perimenopause can begin several years before that point, as hormone levels start to fluctuate and menstrual cycles gradually change.
Most women experience perimenopause somewhere in their 40s, though timing varies. Symptoms can come and go — some months feel completely normal, others feel unpredictable. That inconsistency is actually part of what makes perimenopause tricky to recognise early on.
One thing worth knowing: ovulation can still occur during perimenopause, which means pregnancy is still possible even with irregular cycles. If avoiding pregnancy matters to you, contraception remains relevant until your GP advises otherwise.
Period Changes Are Often One of the First Clues 🩸
Shifts in your menstrual cycle are among the most common early signs of perimenopause. Periods may come closer together or further apart. They might be heavier or lighter, longer or shorter. Some months, you may skip one entirely.
Changes you might notice include:
- Periods arriving earlier or later than your usual pattern
- Bleeding that is noticeably heavier or lighter than normal
- Spotting between periods
- More or fewer bleeding days than you are used to
- Premenstrual symptoms that feel more intense
- Cycles that are harder to predict from month to month
While cycle changes are a recognised part of perimenopause, not every change in bleeding should be put down to hormones. Heavy bleeding, bleeding between periods, bleeding after sex, or any bleeding after menopause should always be discussed with a GP — these may need further assessment to rule out other causes.
Our related article on heavy periods and when to speak with your GP covers when heavier bleeding warrants a check-up and how low iron can become part of the picture.
Hot Flushes and Night Sweats
Hot flushes and night sweats are probably the best-known perimenopause symptoms — and for good reason. A hot flush can feel like a sudden wave of heat rising through the chest, face or body. Night sweats can drench you awake and make it very hard to get back to sleep, leaving you exhausted the next day.
Some women experience these symptoms mildly and occasionally. Others find them frequent and disruptive — affecting work, exercise, relationships and confidence. Neither experience is unusual.
It is worth talking to your GP if hot flushes or night sweats are interfering with your daily life, particularly if they are severe, new, or accompanied by other symptoms like weight loss or fever. Your GP can help work out whether perimenopause is the likely cause and discuss management options that suit your situation.
Sleep, Fatigue and Brain Fog 😴
Sleep becomes more difficult for many women during perimenopause. You might struggle to fall asleep, wake frequently through the night, or find yourself wide awake at 4am with no hope of getting back to sleep. Night sweats can compound all of this.
The knock-on effects are real. Poor sleep affects concentration, memory, patience, appetite, motivation and mood. Many women describe a kind of “brain fog” — feeling less sharp than usual, more forgetful, or slower to find words mid-sentence. It can be frustrating, especially when it shows up in places like work or parenting.
It is also worth knowing that these symptoms can overlap with stress, anxiety, thyroid conditions, low iron, vitamin deficiencies and other health issues. Fatigue that is persistent or feels out of proportion to what you would expect is worth raising. Your GP may suggest blood tests or other investigations to get a clearer picture.
Our article on what happens after a blood test explains how results are interpreted in context — not as isolated numbers.
Mood, Anxiety and Emotional Changes
Changes in emotional wellbeing are common during perimenopause, and they deserve to be taken seriously. Some women notice irritability, low mood, heightened anxiety, tearfulness, or a general feeling of being less resilient than usual. Others describe simply feeling unlike themselves — which can be unsettling when there is no obvious reason for it.
These experiences are real and worth discussing. They should not be dismissed as “just hormones” — but they also should not be ignored on the basis that they might be hormonal. Your GP can help look at the full picture: sleep, stress, life circumstances, mental health history, physical symptoms and the possibility of hormonal change all playing a role.
If mood symptoms are severe, persistent, or affecting your relationships, work or sense of safety, please seek help promptly. Mental health support can be an important and effective part of perimenopause care.
Sexual Health and Vaginal Symptoms
Some women notice vaginal dryness, discomfort during sex, changes in sexual desire, increased urinary frequency or irritation. These symptoms are more common than many people realise — and many are very treatable.
They can feel awkward to bring up, but they are a legitimate part of women’s health care. You do not need to wait until things become severe before asking for help. Your GP can ask about dryness, pain, bleeding after sex, urinary symptoms and sexual wellbeing, and will consider whether STI screening, cervical screening or other assessment would be useful.
The right approach depends on your symptoms, preferences and medical history.
Contraception Still Matters During Perimenopause
Perimenopause does not automatically signal the end of fertility. Ovulation may still happen even when periods are unpredictable, so if you want to avoid pregnancy, contraception still needs to be part of the conversation.
The right option depends on many things — your bleeding pattern, current symptoms, medical history, risk factors and what matters most to you. Some women prefer a method that also helps regulate or reduce bleeding; others want non-hormonal options or need to avoid certain hormones for medical reasons.
Shire Family Medical’s Women’s Health GP Services include contraception counselling, menstrual concerns, menopause support, cervical screening, breast health checks and ongoing advice across all life stages.

Bone, Heart and Longer-Term Health
Perimenopause is not only about managing day-to-day symptoms. It is also a useful time to step back and think about longer-term health.
Changing oestrogen levels after menopause can affect bone density, and midlife is often when other risk factors — blood pressure, cholesterol, blood sugar, weight, sleep, activity levels — start to deserve closer attention.
Depending on your situation, your GP may discuss:
- Blood pressure and cardiovascular risk
- Cholesterol or diabetes risk, where relevant
- Bone health and osteoporosis prevention
- Nutrition, weight and physical activity
- Alcohol, smoking or vaping
- Sleep and mental health
- Cervical screening, breast health and skin checks
Not every woman needs every test. But perimenopause can be a genuinely good moment to take stock of preventive health in a thoughtful, structured way — rather than waiting until something becomes a problem.
When To Speak With Your GP
Book an appointment if symptoms are affecting your quality of life — or if you are simply not sure what is going on and would like some clarity. You do not need to have a dramatic symptom to make the appointment worthwhile.
It is especially important to see a GP if you have:
- Periods that have become very heavy, very unpredictable, or erratic
- Bleeding between periods or after sex
- Any bleeding after menopause
- Hot flushes or night sweats that are disrupting sleep or work
- Persistent fatigue, dizziness or symptoms that suggest low iron
- Mood changes, anxiety or low mood affecting your relationships or daily function
- Vaginal dryness, painful sex or recurring urinary symptoms
- Questions about contraception, menopause hormone therapy or non-hormonal options
- Symptoms appearing before age 45, or possible premature menopause before age 40
If symptoms are sudden, severe or feel medically concerning, do not wait for a routine review — seek care promptly.
What Your GP May Discuss
Your GP will usually begin by hearing your story: what has changed, when you first noticed it, how it is affecting you, and whether anything else might explain it. That context matters.
From there, and depending on your situation, the conversation may cover:
- Your menstrual pattern and any changes in bleeding
- Hot flushes, night sweats and sleep quality
- Mood, anxiety, stress and mental health
- Sexual health, vaginal symptoms and urinary concerns
- Contraception and pregnancy prevention
- Blood tests, if symptoms suggest low iron, thyroid issues or another contributing cause
- Menopause hormone therapy or non-hormonal options, where appropriate
- Preventive health checks, including bone and cardiovascular health
It helps to jot down a few notes beforehand — even a rough list of your periods, sleep patterns, hot flushes, mood and energy levels over the past few months. A short symptom diary can make the appointment more focused and useful for both of you.
Perimenopause Care Should Feel Practical, Not Dismissive
Perimenopause is a normal part of life — and it can still be genuinely hard. Good care does not mean medicalising every change or reaching for treatment automatically. It means taking your symptoms seriously, exploring whether other causes need to be considered, and making decisions together that support your quality of life.
For patients in Sutherland and the broader Sutherland Shire, Shire Family Medical provides GP-led women’s health care across adolescence, the reproductive years, perimenopause and post-menopause.
