Does this sound familiar?
Perimenopause isn't just about hot flashes. It's the cumulative weight of a hundred small changes.
The 3 AM Ceiling Stare
Waking up at 3:14 AM like a light switch flipped. Your heart is racing, your mind is zooming, and sleep is a distant memory.
The Missing Word
You know exactly what you want to say, but the noun is just... gone. You feel like your brain is firing through thick fog.
The Cycle Mystery
Your period used to be a clock. Now it arrives 10 days early, skips two months, or lasts twice as long as it should.
The Invisible Heatwave
A sudden internal fire that starts in your chest and washes over your face at the least convenient moment.

Questions & Answers
Helping you navigate the transition with clarity and confidence.
Periwell is a symptom intelligence and logging tool designed to help you track 40+ perimenopause symptoms using the STRAW+10 clinical framework. While it provides clinician-grade reports, it is not a diagnosis or a replacement for professional medical advice. Always consult your healthcare provider.
Once you have logged symptoms for at least 7 days, you can generate a PDF report. This report translates your subjective feelings into objective data (frequency, severity, and cycle-alignment) that you can hand to your doctor during a 15-minute appointment to skip the guesswork.
Absolutely. We are not an ad product. Your health data is encrypted and we never sell your personal information. You have full control over your data—export it or delete it at any time.
Periwell is currently free to start. Our mission is to close the gap in menopause care by getting this tool into the hands of as many women as possible. We may introduce premium features in the future, but basic symptom tracking and reporting will always remain accessible.
No. In fact, tracking is most useful *before* you have a diagnosis. Many common perimenopause symptoms (like brain fog or anxiety) are often misdiagnosed. Having 3-6 months of logs is the best way to determine if your symptoms are hormonal.
