Ultrasound shows different due date than going by last mentrual cycle due date by 14 days?

When there is a discrepancy of 14 days between the ultrasound-determined due date and the due date calculated from the last menstrual cycle (LMP), it may indicate that the baby is developing at a different rate or that the initial LMP date was inaccurate. Typically, healthcare providers will rely more on the ultrasound measurements, especially if the scan is conducted in the first trimester when fetal growth is more uniform. It's important to discuss this difference with a healthcare provider to determine the most accurate due date and monitor the pregnancy accordingly.
