The ultrasound sheet is the most surprising prenatal examination document for expectant mothers. The bond between expectant mothers and ultrasound has been established since the first three months of pregnancy. From the ultrasound sheet, expectant mothers can observe the overall shape of the fetus and also understand its developmental status. However, there are many expectant mothers who do not know how to understand their gestational age from the ultrasound sheet. So, how to understand the gestational age of the system ultrasound?
System ultrasound is the most common prenatal ultrasound examination, and the gestational age is usually placed at the bottom of the ultrasound single text introduction. Some B-ultrasound scans directly indicate the size of the fetus, which is equivalent to several weeks and days.
Some B-ultrasound scans may display, for example, intrauterine early pregnancy at 6w+2d, where w is the abbreviation for week and d is the abbreviation for day. 6w+2d means six weeks plus two days, which means that the expectant mother is already 44 days pregnant. This is also one way to display the gestational age on the B-ultrasound scan. The gestational age on the ultrasound sheet is an estimate made through ultrasound, and there may be slight differences between the ultrasound gestational age and the clinical gestational age, which is normal.
Generally speaking, the ultrasound data taken by expectant mothers after five months of pregnancy mostly matches the actual gestational age. If the gestational age displayed on the B-ultrasound is significantly different from the actual gestational age of the expectant mother, the expectant mother should first seek confirmation from a doctor to determine if there was an error in the doctor's description. If the doctor's error is ruled out, it is necessary to consider fetal developmental delay and intervene as soon as possible.
