The app gives a 40 weeks default gestational age. Generally, the gestational age is measured from the first day of your last period to the current date in weeks. After the actual gestational weeks and due date are confirmed on ultrasound, you can update the pregnancy date or the due date accordingly.

1. To update your pregnancy record, please tap "Pregnancy History" on the profile page.

2. Tap the pencil icon to edit your "Last Period Start" or "Estimated Due Date", and click Save.

Note: Changing your due date will only change the estimated length of your gestation, not your current gestational age. If you want to update the gestational age, please change the “Last Period Start” to match it. Rest assured that changing it will not revise your real period record, it only updates your pregnancy record.
