At what age do periods stop?
Periods usually stop for good between the ages of 45 and 55, with an average age of about 52 in the US. That point is menopause, confirmed once you've gone 12 months without a period. In the years before it, during perimenopause, periods often become irregular. Menopause before 40 is called premature and should be checked.
The typical timeline
| Stage | Typical age | What happens to periods |
|---|---|---|
| Late reproductive years | late 30s to early 40s | Cycles may get a few days shorter |
| Early perimenopause | early to mid 40s | Cycle length starts to vary by 7 days or more |
| Late perimenopause | mid to late 40s | Gaps of 60 days or more between periods |
| Menopause | around 52 on average (US) | The final period, confirmed after 12 months with none |
| Postmenopause | after that | No periods; any bleeding should be checked |
Everyone moves through these stages at their own pace. Some people's periods stop fairly suddenly; others have years of irregular cycles first. Read more about how long perimenopause lasts and how to know you're in menopause.
What affects when your periods stop
- Genetics: the age your mother or sisters reached menopause is one of the best clues.
- Smoking: tends to bring menopause earlier, often by one to two years.
- Surgery or treatment: removing both ovaries causes immediate menopause; chemotherapy or pelvic radiation can bring it on early.
- Some health conditions: including certain autoimmune and genetic conditions.
- Hysterectomy: periods stop, but if the ovaries stay, hormonal menopause happens at its own time.
Early and premature menopause
When periods stop before 45, it's called early menopause. Before 40, it's premature menopause or primary ovarian insufficiency. It's uncommon, but it happens. It matters because low estrogen for many years raises the risk of weak bones and heart disease, and treatment can protect you.
Your periods stop or become very irregular before 45, you have menopause symptoms in your 30s, or you have any bleeding after 12 months without a period. Bleeding after menopause always needs checking, even if it's just spotting.
Mood and the end of periods
The years before periods stop can be emotionally bumpy. As estrogen rises and falls unpredictably, some people notice more irritability, anxiety, low mood or poor sleep, even if they never had much PMS before. For many, mood steadies once periods have stopped for a while. Our perimenopause mood swings page explains why.
Perimenopause is when tracking is most useful: gaps between periods, hot flashes and mood changes form a picture that helps you and your doctor decide what support you need.
Frequently asked questions
Can you still get pregnant before periods stop completely?
Yes. Until you've had 12 months without a period (2 years if under 50), you may still ovulate occasionally. Use contraception if you don't want to conceive.
Is 45 too early for periods to stop?
Menopause between 40 and 45 is called early menopause. It's not rare, but it's worth seeing a doctor to talk about bone and heart health.
Do periods get heavier before they stop?
For some people, yes. Uneven hormones in perimenopause can cause heavier or longer periods. Very heavy bleeding should be checked.
What's the oldest age periods can stop?
Most people reach menopause by 55. If you're still having periods after 55, mention it to your doctor.
