You may be in perimenopause if your menstrual cycle is changing and/or you’re starting to get symptoms caused by shifting hormone levels, especially irregular periods, hot flashes, or night sweats.[1][2][10]
The most common early clue is a change in your periods: they may become closer together or farther apart, heavier or lighter, or you may skip periods altogether.[1][2][10] Mayo Clinic notes that if your cycle length is consistently different by 7 days or more, that can fit early perimenopause; if you go 60 days or more between periods, that suggests late perimenopause.[2]
Other common symptoms include:
- Hot flashes and night sweats[1][2][4]
- Sleep problems or insomnia[1][2][4]
- Mood changes such as irritability, anxiety, or depression[1][2][4]
- Vaginal dryness or discomfort during sex[1][2][4]
- Low libido[1][5]
- Urinary urgency or more frequent urination[1][12]
- Brain fog, fatigue, or trouble concentrating[5][12][14]
A practical way to check is to track your period pattern and symptoms for a few months. If you’ve had a previously regular cycle and it starts shifting, that is often the first sign.[1][15]
It’s a good idea to see a clinician if:
- Your bleeding is very heavy or lasts much longer than usual[2][5]
- You have bleeding between periods or after sex
- You might be pregnant
- Your symptoms are severe or affecting sleep, work, or mood[1][2]
Doctors usually diagnose perimenopause based on age, symptoms, and period changes rather than a single blood test, because hormone levels can fluctuate a lot during this stage.[2][9]
