Either your ovulation may have been later than expected, or you may be pregnant. If you have confidently predicted and confirmed ovulation and continue to test for pregnancy without success, you may want to check with your medical professional. Since the period prediction is not that accurate when your cycles are irregular, we offer an option to remove the predicted period day.
1. When your period is late, you will see “Remove predicted period” on the Homepage. And the predicted period days on the Calendar page will be circled in light pink color with slashes.
Note: Without logging a period, the app will count the first day of the predicted period as CD1.
2. Tap “Remove predicted period day” then choose "Yes" will change the predicted period day to the next day.
3. After removing the predicted period, the home page and the calendar page update accordingly.
