View menstrual cycle predictions and history in Health on iPhone
When you log your menstrual cycle in the Health app , you can check the date for your next period or fertile window, receive notifications about when your next period or fertile window is approaching, view details about your cycle history, and more.
Note: Health can also use data from Apple Watch to improve the predictions for your period and fertile windows. See Use Cycle Tracking on Apple Watch in the Apple Watch User Guide.
View your cycle timeline
Tap Browse at the bottom right, then tap Cycle Tracking.
At the top of the screen, a timeline shows the following icons.
Icon | Description | ||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
![]() | A predicted period day. | ||||||||||
![]() | A predicted day of your fertile window. | ||||||||||
![]() | A day you likely ovulated (requires Apple Watch Series 8 to be paired with your iPhone; Apple Watch sold separately; not available in all regions). | ||||||||||
![]() | A day you logged a period. | ||||||||||
![]() | A day you added information (for example, noting a headache or cramping). |
To select different days, swipe the timeline.
![The Cycle Tracking screen with a timeline near the top showing an estimated fertile window.](https://help.apple.com/assets/640A52196275DE31D4371B5E/640A52226275DE31D4371B8B/en_US/fbb1219f8f6dc4cd6f78f0d724743300.png)

, then choose an option.
If you receive a Cycle Deviation notification
You can receive a notification if your logged cycle history shows a possible cycle deviation. Irregular periods, infrequent periods, prolonged periods, and persistent spotting are common cycle deviations that may indicate an underlying condition, or may be due to other factors.
When you receive a notification, do the following to review your logged cycle history:
In Health, tap Summary at the bottom of the screen.
Tap Review Cycle History in the Possible Cycle Deviation notification.
Follow the onscreen instructions to confirm, add, or edit the data in your cycle history.
If a cycle deviation is detected, a screen suggests what to do next.
The information you add about yourself in Health is yours to use and share. You can decide what information is stored in Health as well as who can access your data. When your iPhone is locked with Face ID, Touch ID, or a passcode, all of your health and fitness data in Health, other than your Medical ID, is encrypted. Any health data synced to iCloud is encrypted both in transit and on Apple servers. And if you have a version of iOS (and watchOS, if you’re using Apple Watch for cycle tracking) with default two-factor authentication and a passcode, your health and activity data is stored in a way that Apple can’t read it. This means that when you use the Cycle Tracking feature and two-factor authentication, your health data synced to iCloud is encrypted end-to-end, and Apple doesn’t have the key to decrypt the data and therefore cannot read it.
