How to Know If You're in Perimenopause

two women sitting together on white seat. One is wearing red jumpsuit and has long blonde curly hair and the other is wearing a pink suit. Both looking at each other and pulling a face.

You’re doing everything “right” - eating well, moving your body, trying to get enough sleep. And yet, something feels off. Your energy’s unpredictable. Your moods swing. And your period has a mind of its own.

If you’re in your late 30s or 40s and wondering if these changes are normal, the answer might be: yes. 
You could be in perimenopause—the hormonal transition phase before menopause.

What is Perimenopause, Really?

Perimenopause is the body’s natural shift into a new hormonal rhythm. It typically begins in your 40s (sometimes earlier) and can last anywhere from 4 to 10 years.

Unlike menopause—which is defined as 12 consecutive months without a period—perimenopause is a moving target. Oestrogen and progesterone levels rise and fall unevenly, leading to a cascade of changes that can feel confusing, frustrating, and at times, overwhelming.

Common Signs You're in Perimenopause

No two experiences are the same, but here are some of the symptoms many women report:

- Irregular periods – shorter, longer, heavier, lighter, or skipping altogether
- Sleep disruptions – trouble falling or staying asleep, or waking unrefreshed
- Mood swings and anxiety – even if you’ve never struggled with mental health before
- Hot flashes or night sweats – sudden temperature spikes, often at night
- Weight gain and bloating – particularly around the midsection
- Brain fog – forgetting names, losing focus, or feeling mentally “foggy”
- PMS that feels more intense – breast tenderness, irritability, or fatigue

These changes are not “just in your head”—they’re real, hormonal, and valid.


How Is Perimenopause Diagnosed?

Here’s the tricky part: there’s no single test for perimenopause.

Hormone levels fluctuate daily, so blood tests (like FSH or estradiol) can help rule things out, but they won’t always provide definitive answers. Most diagnoses come down to symptoms, cycle tracking, and life stage.

That’s why tracking how you feel—physically, mentally, emotionally—is so powerful. Use a journal or an app to notice patterns. Write it all down: when your sleep changes, how your period behaves, what your energy feels like.


Supporting Your Hormones (Naturally)

While every woman’s experience is unique, these strategies can help ease the transition:
- Balance blood sugar with protein-rich meals and fewer processed carbs
- Move gently and regularly to reduce inflammation and support hormone regulation
- Protect your sleep with calming rituals, magnesium, and consistent routines
- Reduce stress—even five minutes of breathwork or walking can make a difference
