How do I know if I am in perimenopause?

Short answer: You may be entering perimenopause if your periods change and you have menopausal-type symptoms (hot flashes, sleep or mood changes, vaginal dryness, etc.). Perimenopause is usually diagnosed based on your symptoms and menstrual history rather than a single definitive lab test. Here’s how to tell and what to do next.

What to look for

• Menstrual changes (the most reliable sign): cycles become shorter or longer, more or less heavy, or you skip periods unpredictably. Menopause is defined as 12 consecutive months without a period; the years leading up to that are perimenopause.
• Common symptoms: hot flashes/flushes, night sweats, poor sleep, mood swings or anxiety, decreased libido, vaginal dryness or discomfort with sex, urinary frequency/urgency, brain-fog or memory problems, and gradual weight gain.
• Typical timing: most people begin perimenopause in their 40s, but it can start in the 30s or earlier (especially after surgery, chemotherapy, or with smoking).

What tests can and can’t tell you

• Pregnancy test first if you’re still having periods and pregnancy is possible.
• Blood tests sometimes used: FSH and estradiol. However, hormone levels fluctuate during perimenopause, so a single FSH or estradiol level may be misleading. Clinicians usually rely more on symptoms and bleeding patterns.
• Other useful tests: TSH (to check thyroid), CBC if heavy bleeding, and as indicated pelvic ultrasound or Pap if abnormal bleeding. Anti-Müllerian hormone (AMH) can reflect ovarian reserve but is not a clear diagnostic test for perimenopause in routine practice.
• At-home or direct-to-consumer hormone kits (LetsGetChecked, Everlywell, etc.) are available, but results should be interpreted with a clinician because of hormonal variability.

When to see a clinician

• Make an appointment if symptoms interfere with daily life, if bleeding is very heavy or very prolonged, if you have pelvic pain, or if you have any unusual bleeding (after sex or between periods).
• Your primary care doctor or OB/GYN can make a clinical diagnosis, order appropriate tests, and discuss treatment options.

What you can do now

1. Track cycles and symptoms for 3–6 months (use an app like Clue or Flo or a simple calendar).
2. Bring your symptom and bleeding log to your clinician visit.
3. Discuss treatment options if symptoms are bothersome — treatments range from lifestyle measures and vaginal moisturizers to systemic hormone therapy (the most effective for hot flashes) or non-hormonal options (SSRIs/SNRIs, gabapentin, etc.). Vaginal estrogen is very effective for local symptoms. A clinician will weigh benefits/risks for you.

Specific services to consider

• Elektra Health — telehealth menopause specialists who focus on individualized menopause care and can prescribe and manage hormone therapy if appropriate. Good if you want clinicians focused on menopause.
• Gennev — menopause telehealth + coaching and community resources; helpful for symptom management and lifestyle support.
• Maven Clinic — broader virtual women’s health care including menopause; convenient if you prefer a general virtual clinic.
• LetsGetChecked and Everlywell — offer at-home hormone testing panels if you want to see numbers first, but use these only as adjuncts and review results with a clinician.
• Book a visit with your local OB/GYN or a menopause clinic at a major health system for in-person evaluation if symptoms are severe or complex.

When to seek urgent care

• Very heavy bleeding (soaking through one pad/hour for several hours), fainting, severe chest pain or shortness of breath, or signs of infection after procedures—seek urgent/ER care.

If you want, tell me your age, what changes you’ve noticed, and how severe the symptoms are. I can help you decide whether to call a clinician now and suggest which tests or treatments you might ask about.
