When we hear “perimenopause,” we picture women in their late 40s or 50s.
But more women in their 30s are asking whether that’s what they’re going through, and sometimes the answer is yes.
What is perimenopause?
It’s the transition before menopause, when hormones start to fluctuate. It starts between two and seven years before menopause, so symptoms can show up as early as the late 30s.
Most women notice the first changes in their 40s, but timing varies. Family history matters most: your mother’s age at menopause is the strongest predictor.
Signs to watch for
- Period changes. Cycles get shorter, longer, heavier or lighter. Clinicians treat a persistent difference of seven days or more between cycles as a sign the early transition has begun.
- Sleep trouble. This is often one of the earliest symptoms, sometimes before cycle changes.
- Mood shifts. Anxiety, irritability, low mood, or feeling less able to handle stress.
- Brain fog. Forgetting words, trouble focusing.
- Body changes. Hot flashes, night sweats, joint pain, migraines, breast tenderness, worse PMS.
- Heart palpitations. One doctor notes palpitations or anxiety attacks can appear before hot flushes.
Why It Gets Missed
Many women are told it’s stress or burnout.
In one 2025 US survey, nearly 40% of women reported being misdiagnosed, and more than half were treated for anxiety, depression or panic attacks instead.
Antidepressants are right for real depression and anxiety. The point is that hormones should also be considered.
It Might Not Be Perimenopause
Thyroid problems, anaemia, PCOS, stress and nutritional deficiencies can cause similar symptoms. That’s why a checklist from social media isn’t a diagnosis.
If symptoms start before 40, doctors may also look at premature ovarian insufficiency (POI). Menopause before 40 affects roughly 1 in 100 women, and it matters because of bone and heart health.
What To Do
- Track for 2–3 months: period dates, flow, sleep, mood, hot flashes.
- See a doctor if symptoms persist or disrupt daily life, and bring your notes. Ask directly: “Could this be perimenopause?”
- Ask for a specialist if you feel dismissed.
- Don’t skip contraception if you’re avoiding pregnancy. The ovaries often still release eggs in early perimenopause, so pregnancy is still possible.
At the end of the day, if you’re feeling it, you’re not imagining it, and you’re not necessarily too young. It is always better to get checked rather than guessing.
