What is a pregnancy tracker?
A pregnancy tracker is an app or guide that organises a pregnancy by gestational week. It can help you keep the week number, due date, notes, personal records, and memories together so they are easier to find later.
The American College of Obstetricians and Gynecologists (ACOG) explains that pregnancy is counted from the first day of the last menstrual period and averages 40 weeks. Your healthcare provider may adjust the dates using information that is specific to your pregnancy. Read the ACOG explanation.
A tracker is for context and organisation. It cannot assess symptoms, confirm that something is normal, or replace prenatal care.
What can you track in BabyBerry?
Your week and baby-growth milestone
See the current pregnancy week, a fruit-sized comparison, and a plain-language overview of that stage.
Questions and appointment notes
Write down what you want to remember or bring to your next appointment instead of relying on memory.
Personal records
Keep weight, blood pressure, checkup notes, and other measurements in one timeline. BabyBerry stores what you enter; it does not interpret the readings.
Kick counts and bump photos
Keep movement notes and private photos alongside the rest of your pregnancy timeline. Follow your healthcare provider's instructions if they ask you to monitor movement.
How to choose a pregnancy tracker
The most useful tracker is the one you can understand, trust, and keep using. Before downloading, look for:
- Clear week-by-week information that states its limits.
- A privacy policy that explains who operates the app and how data is handled.
- Simple tools that match what you actually want to remember or discuss.
- A visible distinction between general information and guidance from your own healthcare provider.
