You may be in perimenopause if your periods start changing and you begin having symptoms like hot flashes, night sweats, sleep problems, mood changes, or vaginal dryness.[2][3][6] It usually starts in your 40s, but it can begin earlier or later.[2][6][7]
The most common early clue is a change in your menstrual cycle: periods may become shorter, longer, heavier, lighter, more frequent, less frequent, or skipped.[2][3][5][6] Mayo Clinic notes that if your cycle length is consistently different by 7 days or more, that can suggest early perimenopause; going 60 days or more between periods suggests late perimenopause.[6]
Other common signs include:
- Hot flashes and/or night sweats[2][3][5][6]
- Trouble sleeping or insomnia[2][3][5][6]
- Mood swings, irritability, anxiety, or depression[2][3][5][6]
- Vaginal dryness or discomfort during sex[3][5][6]
- Brain fog, fatigue, or lower libido[1][5]
You usually do not need a test to know you’re in perimenopause, because hormone levels fluctuate and blood tests are often not very helpful for confirmation.[2][4] Doctors may order tests such as FSH, estrogen, or thyroid (TSH) if another condition could be causing similar symptoms.[2]
A practical way to check is to track your periods and symptoms for a few months in a calendar or period app and then discuss the pattern with a clinician.[4] If you have very heavy bleeding, bleeding between periods, bleeding after 12 months without a period, or symptoms that significantly affect your life, see a healthcare professional.[4][6]
If you want, I can also help you figure out whether your symptoms sound more like perimenopause vs. thyroid issues vs. pregnancy.
