We suggest starting by logging the dates of your next period. To do this, tap the pink Log Period button for the required day on the main screen. The number of days indicated in Menu > Cycle and Ovulation will be marked as your period.
To edit your period dates, tap the month in the top right corner and tap Edit Period Dates. Then check the required dates and save.
When you scroll to the next month, you’ll see days marked with different colors:
- Predicted period days are marked in red.
- Predicted fertile days are marked in teal. A day that is inside a teal dotted circle is your predicted ovulation day — and it says High chance of getting pregnant. A few days before ovulation and a couple of days after are days marked as Chance to get pregnant. To make these predictions, the app considers various parameters, such as the sperm can survive for up to five days in the female body, and your egg can survive for 24 hours. It tries to keep the fertile window as wide as possible to include all possibilities.
- The days that are black (after the ovulation and before the next period) have a low chance of pregnancy. However, the chance of getting pregnant still exists even during the low-chance phase, as your cycle may shift for a variety of reasons.
For the current and past days, it’s also possible to add symptoms and events. Flo offers 16 trackers with more than 50 symptoms and events to log. To add your symptoms for today, tap “+” at the bottom left corner of the main screen. To see all available trackers and customize the symptoms screen for yourself, scroll down and tap More parameters. The more symptoms you enter, the more precise predictions you will receive.
To get an overview of the logged data for your current and past cycles, navigate to Menu > Graphs & Reports.
All information you log will personalize Flo’s insights for you. You’ll get information about your current cycle day and your added symptoms in stories.
Flo Health Assistant will offer dialogs on the information you log and the events in your cycle, such as your period, ovulation, delays, and more. If you have a specific goal in the app — get pregnant or track your pregnancy, for example — we suggest you set it in Menu > My goal. For each goal, Flo offers additional functions, plenty of relevant content in Insights, and personalized daily plans in stories.
If you would like to always be ready for your next period, know when your ovulation is predicted, or start a new good habit — for example, drinking water — go to Menu > Reminders and enable notifications for the events that are important to you.
Please, note that the app is not intended to serve as a method of birth control or contraception.
