Why Knowing Your Due Date is Important
Understanding your due date helps you plan prenatal care, prepare for the baby’s arrival, and schedule important medical appointments. It also allows you to manage your time effectively, ensuring you’re ready for one of life’s most wonderful events.
What is a due date?
A due date is the estimated day your baby will arrive. Doctors calculate this date as 40 weeks from the first day of your last period. Only about 5% of babies actually arrive on their exact due date. Most babies come within one to two weeks before or after this date.
How do doctors calculate the due date?
Doctors use a method called Naegele’s rule to find your due date. They take the first day of your last menstrual period, add one year, subtract three months, then add seven days. For example, if your last period started on February 1, your due date would be around November 8. Ultrasounds in early pregnancy can also help set or adjust this date.
Why might my due date change during pregnancy?
Your due date might change if an early ultrasound shows the baby’s size does not match the date based on your last period. This often happens if you have irregular cycles or if you were not sure about your last period date. The date from an early ultrasound (before 14 weeks) is usually more exact.
What happens if I go past my due date?
If you go past your due date, your doctor will watch you more closely. They might do more tests to check your baby’s health, like non-stress tests or ultrasounds to check amniotic fluid levels. Most doctors will talk about ways to start labor if you reach 41 or 42 weeks, since risks to the baby can increase after this point.
