Most of these symptoms are treatable. A blood test can rule out look-alikes such as thyroid disease.
How it works
- It reads your periods first. Early perimenopause starts with cycles varying by a week or more; a gap of 60 days or more can be a sign of middle to late perimenopause; menopause means 12 months in a row without a period.
- Then it weighs your age and how many symptoms you checked. Symptoms can start before cycles change, so from 35 up, two or more symptoms with regular periods count as a possibility; from 40 up, if your period pattern can't be used, any symptom makes perimenopause likely enough to be worth a proper evaluation.
- Pregnancy, breastfeeding, chemotherapy, ovary removal, hormonal contraception, a thyroid condition and heavy bleeding change the result or add a note.
Frequently asked questions
Can a test tell me if I'm in perimenopause?
No. Perimenopause is a clinical diagnosis from age, symptoms and period pattern; FSH swings month to month, so one result settles nothing. Testing helps under 40, with no periods to track (hysterectomy or hormonal IUD), or when thyroid or something else could explain symptoms.
At what age does perimenopause start?
Mid-40s on average, with some women starting in their late 30s. Menopause averages 51 in the US, and 45 to 55 is normal.
Can I be in perimenopause with regular periods?
Yes, early on. Early perimenopause starts with cycles varying by a week or more, often shortening first, and symptoms like sleep trouble and mood changes can arrive while periods still look regular.
How long does perimenopause last?
It lasts until menopause, often 4 to 10 years, depending on when your periods stop for good.
Can I get pregnant in perimenopause?
Yes. Fertility is low but not zero until 12 months without a period. Use hormonal or non-hormonal contraception until 12 months after the last period if you are over 50, or 24 months if you are under 50. Hormone therapy is not contraception.
