Ovulation occurs in the last couple of days of your fertile window. Manually entering ovulation can shift your fertile window and is only recommended if your healthcare provider has confirmed your ovulation date or if you are certain based on your symptoms.
To manually enter ovulation:
> Go to "Calendar" in the bottom bar
> Select the day that you ovulated
> Below the calendar where the symbol key is located, tap “Add ovulation” underneath the dot labeled “Ovulation”
> To remove ovulation, select "Remove ovulation" or "Remove" in the same place where you previously selected "Add ovulation"
