Why can't I change the week of pregnancy?

Flo calculates gestational age from the first day of your last period. If your gestational age is proven to be greater than Flo shows, you can change it by following these steps:

1. Tap Menu (your avatar) > Pregnancy settings > I’m no longer pregnant > Remove pregnancy information > Remove.
2. Tap the Calendar in the top right corner > Edit period dates > Uncheck your last period > Save.
3. Enable Pregnancy Mode again.

Is it safe to edit the pregnancy week?

The option of deleting or editing your last logged period is the only possible way to make the gestational age greater than what the app allows at the moment. However, you don’t have to worry about your logged data. If you delete the pregnancy and your last period, it will not affect any symptoms, notes, or other data that you’ve logged during your pregnancy. When you activate Pregnancy Mode again, you’ll be able to set the correct gestational age and due date.
