If you are pregnant in July, your due date will be in March or April of the following year. In addition to the projection based on the last menstrual period, the expected date of delivery can also be projected based on the results of ultrasound, mainly based on the fetal femur length, biparietal diameter, head circumference, abdominal circumference to assess, because every stage of fetal physical development has a certain reference value, you can assess the specific size based on the reference value, and then analyze the expected date of delivery.
