Pregnancy calendar questions
How do I make a pregnancy calendar?
Enter your due date or the first day of your last period above. Nine Moons works out every week of your pregnancy with its dates, your baby's size, and when your scans, tests and vaccines usually happen.
Can I add my pregnancy dates to my phone calendar?
Yes. Tap "Add key dates to my phone calendar" to download a calendar file with 11 key dates, such as your scan windows, glucose test and due date. Open it on your iPhone, Android phone or computer to add them.
Why does my pregnancy week start on a different day?
Pregnancy weeks are counted from the first day of your last period, so each new week starts on that same weekday.
Are the scan and test dates exact?
No. They are the usual time windows. Your hospital or clinic will give you your actual appointments, and they always come first.
