Determining your expected date of delivery (EDD) is a significant milestone in pregnancy. While several methods exist, using an ultrasound, especially in the early stages, provides a reliable estimate. This article explores the role of ultrasound in calculating your EDD and how our Pregnancy Calculator & Ovulation Estimator can assist you throughout your pregnancy journey.

Calculate Your Due Date →Why Use an Ultrasound to Determine Your Due Date?
Ultrasound scans offer a visual assessment of the fetus, allowing healthcare providers to measure its size and development. This is particularly useful in cases where the last menstrual period (LMP) is uncertain or irregular.
- Accuracy: Early ultrasounds, typically performed in the first trimester, are highly accurate in determining gestational age.
- Irregular Cycles: For women with irregular menstrual cycles, ultrasound provides a more precise dating method than relying solely on LMP.
- Confirmation: Ultrasound can confirm the viability of the pregnancy and rule out certain complications.
How Does an Ultrasound Calculator Work?
The "expected date of delivery by ultrasound calculator" utilizes the gestational age determined during an ultrasound scan. Key measurements, such as the crown-rump length (CRL) in the first trimester or head circumference, abdominal circumference, and femur length in later trimesters, are used to estimate gestational age and, consequently, the EDD.

When is Ultrasound Dating Most Accurate?
Ultrasound dating is most accurate early in pregnancy, ideally between 8 and 11 weeks. The later the ultrasound, the less accurate the due date determination, as babies grow at different rates.
What if My Ultrasound Due Date Differs from My LMP Due Date?
It's not uncommon for the ultrasound EDD to differ from the LMP-based EDD. If the difference is significant (more than 5-7 days in the first trimester), your healthcare provider will likely adjust your due date based on the ultrasound findings, as it's considered more reliable.
