Pregnancy dating calculator

Every pregnancy is unique and your baby will come when it's ready.

Be sure to talk to your health care provider about your due date.

If you deliver on your due date, your baby is actually only 38 weeks old, not 40.

Please remember that your due date is only an estimate.

Now is the time to really watch your diet – not only to give you nutritious, energy giving foods, but also to make sure you are avoiding anything that could be harmful to your baby.

Check out our diet and health in pregnancy pages for ideas for healthy meals and which foods to give a wide berth at this stage.

A normal pregnancy can last anywhere between 38 and 42 weeks.
