Perimenopause does not follow one fixed pattern. Some people notice changes in their periods first, while others experience hot flushes, sleep problems or mood changes.
Symptoms can also change over time. You might have several symptoms one month and very few the next.
Perimenopause in Your 40s
For many people, the first signs of perimenopause appear during the 40s.
Your periods may become less predictable. The time between periods can become shorter or longer, and bleeding may become heavier or lighter.
Other symptoms may include hot flushes, night sweats, sleep problems, headaches and changes in mood.
Later Changes During Perimenopause
As perimenopause progresses, periods often become less frequent. However, the pattern is not always predictable.
You may go several weeks or months without a period and then have another one. Ovulation can also become less regular.
Hot flushes, night sweats, sleep changes and other symptoms may continue, become less noticeable or change in intensity.
Symptoms Are Different for Everyone
You do not need to experience every common symptom to be going through perimenopause.
Some people have very few symptoms. Others experience several symptoms that affect their everyday lives.
Conditions such as thyroid problems, certain medications and other health issues can cause symptoms that look similar to perimenopause. A new or severe symptom should not automatically be blamed on hormones.
Can Tracking Help?
Tracking your periods and symptoms can help you understand how your body is changing.
You can record
• Period dates
• Bleeding changes
• Hot flushes
• Sleep
• Mood
• Pain
• Other symptoms
Looking at several months of information may make patterns easier to recognise. It can also give your healthcare professional useful information if you need an appointment.
When Should You Get Medical Advice?
Very heavy bleeding, bleeding between periods or bleeding after sex should be assessed.
You should also speak with a healthcare professional if symptoms are severe, new or affecting your daily life.
Perimenopause is a normal stage of life, but that does not mean you have to ignore symptoms that are difficult to manage.

No. Other causes are possible, so unusual or persistent bleeding should be assessed.
Can perimenopause affect sleep?
Yes. Sleep problems can occur directly or because of symptoms such as night sweats.
