Due Date Calculator

A Due Date Calculator uses the Naegele’s Rule, which adds 280 days (40 weeks) to the first day of the last menstrual period (LMP). Alternatively, if the conception date is known, it calculates the due date by adding 266 days (38 weeks) to that date.

Knowing your due date helps you prepare for the baby’s arrival, schedule prenatal appointments, and monitor the baby’s development. It also allows healthcare providers to track the pregnancy’s progress and identify any potential complications.

A Due Date Calculator provides an estimated due date, but only about 5% of babies are born on their exact due date. Most babies are born within two weeks before or after the estimated date. Factors like irregular cycles or late ovulation can affect accuracy.

If you have irregular periods, a Due Date Calculator may be less accurate. In such cases, an ultrasound scan during the first trimester is the most reliable way to determine the due date.

The due date is the estimated date of delivery, while the conception date is the day the baby was conceived. The due date is typically calculated by adding 280 days to the first day of the last menstrual period (LMP).

No, a Due Date Calculator cannot determine the baby’s gender. Gender is determined by chromosomes and can be confirmed through ultrasound or genetic testing, usually after 18–20 weeks of pregnancy.

A trimester is a three-month period during pregnancy. The first trimester is weeks 1–12, the second is weeks 13–26, and the third is weeks 27–40. The due date marks the end of the third trimester.

Babies born before 37 weeks are considered premature and may require special medical care. A Due Date Calculator helps you monitor the pregnancy and prepare for early delivery if necessary.

Yes, for IVF pregnancies, the due date is calculated based on the embryo transfer date. A Due Date Calculator can provide an accurate estimate by adding 266 days to the transfer date.

A Due Date Calculator helps healthcare providers schedule prenatal tests, ultrasounds, and checkups at the right times. It ensures the baby’s development is monitored closely throughout the pregnancy.

Yes, a Due Date Calculator can estimate the due date for multiple pregnancies (twins, triplets, etc.). However, multiple pregnancies often result in earlier delivery, so the due date is more of a guideline.

A post-term pregnancy is one that extends beyond 42 weeks. A Due Date Calculator helps identify post-term pregnancies, which may require medical intervention to ensure the health of the mother and baby.
