You may be in perimenopause if your periods become irregular and you start noticing symptoms like hot flashes, night sweats, sleep trouble, mood changes, or vaginal dryness.[3][7][8]
The most common early sign is a change in your menstrual cycle: periods may come sooner or later, be heavier or lighter, or you may skip periods.[2][3][5][7] Mayo Clinic notes that if your cycle length is consistently different by 7 days or more, that can fit early perimenopause; going 60 days or more between periods suggests late perimenopause.[7]
Other symptoms that commonly show up during this transition include:
- Hot flashes and night sweats[3][5][7][8]
- Sleep problems or insomnia[3][5][6][8]
- Mood changes such as irritability, anxiety, or depression[2][3][5][6]
- Vaginal dryness or discomfort during sex[3][5][6][7]
- Brain fog, fatigue, or low libido[2][6]
A doctor usually does not need blood tests to diagnose perimenopause, because hormone levels fluctuate a lot during this stage and testing is often not helpful.[4][5] In some cases, a clinician may check for other causes of similar symptoms, such as thyroid problems or abnormal bleeding.[5]
You should contact a healthcare professional sooner if you have:
- Bleeding or spotting between periods[2]
- Bleeding after sex[2]
- Heavier-than-usual bleeding or periods that last longer than usual[2][4]
- Symptoms that are affecting your quality of life[4][7]
A practical way to tell is to track your periods and symptoms for a few months so you can see whether a pattern is emerging.[4]
