What are the key early signs and symptoms of menopause?
Menopause is a natural life stage—but the lead-up to it can feel anything but straightforward. Many people expect hot flushes to be the first clue, yet for lots of women the earliest changes are more subtle: your cycle becomes unpredictable, sleep goes off track, or you feel “not quite yourself” for months before you join the dots.
In this guide from Medicine Drop Pharmacy, we’ll cover the key early signs and symptoms of menopause, why they happen, and when it’s worth speaking to your GP—so you can feel more informed and supported.

Menopause vs perimenopause: what’s the difference?
Perimenopause is the transition phase before menopause. Hormone levels (particularly oestrogen and progesterone) begin to fluctuate, and symptoms can start months or years before your periods stop.
Menopause is reached when you’ve had no periods for 12 months (and you’re not pregnant or on certain hormonal treatments that stop bleeding). In the UK, the average age of menopause is 51.
Some women experience menopause earlier. If it happens before 40, it may be premature ovarian insufficiency (POI), and it’s important to seek medical advice. The NHS explains menopause and early menopause in more detail here: NHS – Menopause.
How early do symptoms start—and how long do they last?
There’s a wide “normal” range. Some people notice symptoms in their early-to-mid 40s; others later. Symptoms often continue for a while after your final period—commonly several years, though for some they last longer.
The key thing to know: you don’t need to be having hot flushes to be in perimenopause. Early symptoms can be physical, emotional, cognitive—or a mix.
Key early signs and symptoms of menopause (and what they can feel like)
Below are some of the most common early signs. You may experience only a few, and they can come and go.
1) Changes to your periods (often the earliest sign)
Many women first notice their cycle is no longer predictable. You might have:
- Longer or shorter cycles
- Heavier or lighter bleeding
- Spotting between periods
- Skipped periods, then a “normal” one again
Why it happens: ovulation becomes more irregular as hormone patterns shift.
Worth knowing: period changes can have other causes too—stress, thyroid issues, fibroids, certain contraception, and more.
When to speak to a GP: if bleeding is very heavy, happens after sex, occurs between periods repeatedly, or if you’re worried. If you’ve reached menopause (12 months without periods) and bleed again, this should be checked.
2) Hot flushes (hot flashes)
Hot flushes can feel like a sudden wave of heat that spreads through your chest, neck and face. You might also notice:
- Sweating
- A flushed, red face
- A racing heart
- Feeling chilly afterwards
Some women get occasional flushes; others have them multiple times a day.
Tip: triggers can include alcohol, spicy food, caffeine, stress and warm environments. Keeping a quick symptom diary can help you spot patterns.
3) Night sweats
Night sweats are essentially hot flushes that happen at night. They may wake you up feeling drenched or overheated, leaving you tired the next day.
Why it matters: night sweats can be a major driver of fatigue, irritability and low mood—sometimes more than the flushes themselves.
If sleep is becoming a struggle, see our sleep support hub and consider discussing options with your GP.
4) Sleep problems (even without flushes)
Perimenopause can disrupt sleep in a few ways:
- Waking in the early hours and not being able to drop off again
- Light, restless sleep
- Trouble falling asleep (often linked to anxiety)
Why it happens: hormone fluctuations can affect temperature regulation, mood and stress response—each of which can disturb sleep.
External reference: the NHS covers sleep disturbance as a common symptom: NHS – Symptoms of menopause.
5) Mood changes, anxiety, or feeling low
Many women describe emotional changes that feel “out of character”, such as:
- Irritability or tearfulness
- Feeling overwhelmed
- Increased anxiety
- Lower mood or loss of confidence
Important: menopause can overlap with stressful life stages (caring responsibilities, work pressure, teenagers, ageing parents), which can intensify symptoms.
Support that can help: talking therapies—especially CBT—can help with low mood/anxiety and may also reduce how disruptive flushes and sweats feel for some people. NICE discusses options here: NICE guideline NG23 – Menopause: diagnosis and management.
If you ever feel unable to cope, or have thoughts of self-harm, seek urgent medical support.
6) “Brain fog” (memory and concentration changes)
Forgetfulness during perimenopause is common. You might notice:
- Difficulty concentrating
- Losing your train of thought
- Forgetting names or why you walked into a room
- Feeling mentally “slower” at times
What helps: improving sleep, reducing stress, staying active, and addressing flushes/night sweats often improves cognitive symptoms too.
If memory problems are severe or getting worse, speak to your GP to rule out other causes.
7) Vaginal dryness, discomfort, or pain during sex
This one is extremely common—and often under-discussed.
You may notice:
- Dryness, itching, burning or soreness
- Pain during sex
- Light bleeding after sex (from fragile tissues)
- Recurrent irritation that feels like thrush but keeps coming back
Why it happens: lower oestrogen can make vaginal tissues thinner and less lubricated.
What can help: vaginal moisturisers and lubricants can be very effective, and some women benefit from local vaginal oestrogen (prescribed). Explore practical options in our guide to vaginal dryness support.
External reference: NHS – Vaginal dryness.
8) Bladder changes (urgency, frequency, UTIs)
Hormonal changes can also affect the urinary tract. Some women notice:
- Needing to wee more often
- Increased urgency
- More frequent UTIs
- Discomfort that mimics infection
If you have burning, fever, back pain, or you’re pregnant, seek medical advice promptly.
You may find it helpful to read our guide on UTI symptoms and support.
9) Reduced sex drive (libido changes)
A lower libido can be linked to:
- Hormonal shifts
- Vaginal dryness or pain
- Poor sleep and fatigue
- Stress, anxiety, or low mood
This symptom is common and valid. If it’s affecting your relationship or wellbeing, a GP (or menopause specialist) can talk through options—often a combination approach works best (e.g., addressing dryness + sleep + mood).
10) Heart palpitations (a fluttering or racing feeling)
Some women experience palpitations during perimenopause—often alongside anxiety or hot flushes.
Important: palpitations can have many causes. If they’re new, persistent, or accompanied by chest pain, dizziness, fainting, or shortness of breath, seek urgent medical advice.
Other early symptoms you might notice (common, but less talked about)
Not everyone gets these, but they can show up early:
- Headaches or migraines becoming more frequent
- Aches and joint pain
- Skin changes (dryness, itchiness, breakouts)
- Hair changes (thinning or texture changes)
- Weight changes (often around the middle)
Because these symptoms are not “uniquely menopause”, they’re easy to dismiss—especially when you’re busy. If several appear together at the same time as cycle changes, perimenopause becomes more likely.
How is menopause diagnosed in the UK?
In many women over 45, a GP can often diagnose perimenopause/menopause based on symptoms and period changes, without blood tests. This is because hormone levels fluctuate day to day, so a single test may not reflect what’s happening overall.
If you’re under 45, your GP may consider blood tests to explore early menopause/POI and rule out other causes (such as thyroid problems).
You can read more about diagnosis and support here: NHS – Menopause.
When should you seek medical advice urgently?
Book a GP appointment (or seek urgent care when appropriate) if you have:
- Bleeding after menopause (after 12 months with no periods)
- Very heavy bleeding, bleeding after sex, or persistent intermenstrual bleeding
- Severe mood symptoms, panic, or depression
- Palpitations with chest pain, breathlessness, fainting, or dizziness
- Symptoms you’re unsure about, or anything that feels suddenly worse
What can help? Practical support and treatment options
There isn’t a one-size-fits-all approach. Many women combine lifestyle changes with targeted treatments.
Lifestyle steps that often make a difference
- Keeping your bedroom cool; breathable bedding
- Cutting down alcohol (especially if it triggers flushes)
- Regular movement (helps mood, sleep and joint aches)
- Strength training for bone and muscle health
- Stress support (CBT, mindfulness, counselling)
Medical options (discuss with your GP)
- HRT (Hormone Replacement Therapy) can be very effective for hot flushes, night sweats, sleep and quality of life for many women (not suitable for everyone). NICE guidance: NG23.
- Vaginal oestrogen for vaginal and urinary symptoms (often used long-term).
- Non-hormonal options may be considered in certain situations (e.g., if HRT isn’t suitable).

A simple way to track symptoms (useful for GP appointments)
For 2–4 weeks, jot down:
- Period dates + flow changes
- Hot flush/night sweat frequency
- Sleep quality
- Mood (0–10)
- Any urinary/vaginal symptoms
- Triggers (alcohol, stress, caffeine, warm rooms)
This can help you and your GP see patterns and choose the most appropriate support.
Frequently asked questions
Can you still get pregnant during perimenopause?
Yes. Pregnancy is still possible until menopause is reached (12 months without periods). If you don’t want to conceive, discuss contraception with your GP.
Is it normal to have symptoms but still have periods?
Yes—this is very common in perimenopause. Many symptoms start well before periods stop.
Do all women get hot flushes?
No. Some women have few or no flushes and mainly notice mood, sleep, brain fog or vaginal symptoms.
Final thoughts
The early signs of menopause can be confusing—especially when symptoms creep in gradually. If you’re noticing a cluster of changes (particularly cycle changes + sleep disruption + mood shifts + flushes/sweats), perimenopause may be the reason.
You don’t have to “just put up with it”. Support is available, and many women feel significantly better with the right plan. If you’d like to explore options, Medicine Drop Pharmacy is here to help with trusted information and everyday symptom support—alongside advice from your GP.
