Why can’t I see ovulation predictions?

Your ovulation and fertile window predictions can disappear from the calendar for several reasons:

1. Fertile window predictions disappear if you start tracking hormonal contraception, as it suppresses ovulation. To check if a contraception reminder is enabled, go to Menu (your avatar) > Reminders > Contraception. If it’s been activated by mistake, just disable the reminder, and predictions will resume.
2. Your cycle was predicted to last for less than 20 days or more than 60 days. Flo is unable to give ovulation predictions for cycles that are very short or very long. Therefore, we hide them in this instance so we don’t mislead you. Once your cycle is somewhere between 21 and 60 days long, and the app notices this trend, ovulation predictions will resume. If your cycle is very short or very long, we suggest tracking your ovulation via basal body temperature and ovulation tests.
3. Your period is delayed. If a delay is displayed in your calendar, then ovulation and period predictions for future months are hidden. Once you log a new period, and the app receives new information, predictions will be recalculated and displayed again.
4. You disabled the chance of getting pregnant. Once it’s turned off, only ovulation days are displayed. If you want to see your predictions again, you can simply enable the parameter in Menu (your avatar) > Cycle and ovulation.
