3. Your due date is an estimate, it is an average. In the chart below you can see the reality. In week 38, 2 weeks before the due date, 2 out of 10 women will give birth.

In week 39, 1 week before the due date, 2 out of 10 women will give birth.

In week 40, the due date, 3 out of 10 women will give birth.

In week 41, 1 week after the due date, 2 out of 10 women will give birth.

It is very unlikely that your baby will gestate for longer than 42 weeks. In such cases, estimated due dates may have been incorrectly calculated.
