1. Ultrasound dating: An ultrasound scan can accurately determine the gestational age of the fetus, which can then be used to calculate the expected due date. This method is considered one of the most accurate ways to determine the expected date of delivery.
2. Last menstrual period (LMP): By calculating the first day of the last menstrual period and adding 280 days (40 weeks), healthcare providers can estimate the expected due date. This method is commonly used when the exact date of conception is unknown.
3. Fundal height measurement: Healthcare providers can measure the size of the uterus by measuring the distance from the pubic bone to the top of the uterus (fundus). This measurement can help estimate the gestational age and expected due date.
4. Pregnancy wheel: A pregnancy wheel, also known as a gestation calculator, is a tool that healthcare providers use to quickly estimate the expected due date based on the first day of the last menstrual period. This method is simple and easy to use.
5. Blood tests: Certain blood tests, such as the levels of human chorionic gonadotropin (hCG) or pregnancy-associated plasma protein-A (PAPP-A), can help determine the gestational age and expected due date. These tests are often used in conjunction with other methods to confirm the estimated due date.

1. Naegele's Rule:
- Most common method
- Count back 3 months from the first day of the woman's last menstrual period (LMP) and add 7 days
Formula: EDD = LMP - 3 months + 7 days
2. Ultrasound:
- Transvaginal ultrasound in early pregnancy can measure the size of the embryo or fetus
- Measurements are used to estimate gestational age and predict the EDD
3. Fundal Height Measurement:
- Measuring the distance from the top of the uterus to the pubic bone
- Can be used to estimate gestational age after 20 weeks of pregnancy
4. Fetal Heart Rate (FHR) Monitoring:
- FHR increases with gestational age
- Using a Doppler device to monitor the FHR can help estimate the woman's due date
5. Fetal Movement Monitoring:
- Women typically start feeling fetal movements between 16-22 weeks of pregnancy
- The timing and frequency of movements can be used to estimate gestational age
- Most common method
- Count back 3 months from the first day of the woman's last menstrual period (LMP) and add 7 days
Formula: EDD = LMP - 3 months + 7 days
