Did you know?
74%
of women in perimenopause are never told that's what's happening. Symptoms get blamed on stress, anxiety, or simply "getting older."
"I thought I was anxious and burned out. I had no idea the night sweats, the 3am panic, and the brain fog were all the same thing." — r/perimenopause

About timing
4–8 yrs
The average perimenopause lasts 4 to 8 years — though it can range from 1 to over 10. Symptoms typically intensify in the 1–2 years before the final period.
Average onset
47.5
Average age perimenopause begins in the US — though 10% of women enter before 45. Source: SWAN Study 2022.
"Three years of this before someone actually told me what it was. My GP kept saying my bloodwork was normal." — r/Menopause
Step 3 of 4

Have you spoken to a doctor about what you're experiencing?

Your answer shapes how we present your results — and what resources will be most useful to you.

Yes — and they were helpful
I have a provider who understands what's happening
Yes — but I felt dismissed or not heard
My concerns weren't taken seriously
Not yet — I haven't made an appointment
I'm still figuring out what to say
I'm not sure it's worth bringing up
I don't want to waste their time
You are not alone
74%
of women with perimenopause symptoms are never formally told that's what they have. Many are told their bloodwork is "normal" or are offered antidepressants without a hormonal workup.

Your symptom pattern

These symptoms together
have a clinical name.

What you're describing — the hot flashes, sleep disruption, anxiety, and brain fog — is a recognised pattern of vasomotor perimenopause. It is caused by fluctuating estrogen affecting your brain's temperature and mood regulation. You are not imagining this. This is not stress. This is biology.
