In the Bellabeat app, you will be able to log your periods and have the app calculate the dates of your next period and fertile days, based on the past periods that you input into the app.
When you first load the app on your phone, you will see the period tracking ribbon on the app’s home screen. When you tap it, you can either select not to have your period tracked or you can input data about your last period and your usual cycle length and the length of your period.
When you’ve done that, you will see your cycle presented in the form of a circle. The beginning of the circle will be the first day of your period and the red drops will indicate the days that your period has lasted. The purple stars indicate your fertile days and the purple oval is your ovulation day.
You can move your finger across the circle to see the dates when your next period is predicted and when your fertile days are.
When you start your period, you will need to press the "Start period" button in the app and when your period ends, you only need to press the "End period" button. In case your period continues the day after you ended it, you can simply press the "Extend period" button for that day.
You can also track your pregnancy in the Bellabeat app and you can do that by pressing the Settings button on the Period tracking screen and inputting the start date of your pregnancy. The Leaf app will do the rest.
In case you want to edit any of your previous cycles, you will need to press the clipboard icon in the upper right corner and tap the period you want to edit, edit the dates and hit the checkmark icon.
