There is nothing good or bad about an ultrasound being a week older than the actual week of pregnancy, it is normal for the ultrasound to be about a week older or smaller than the actual week of pregnancy. A week larger than the actual week of pregnancy may be due to a woman’s shorter menstrual cycle, earlier ovulation, and earlier implantation of the fertilized egg. It may also be due to the better nutritional status of the pregnant woman and the better development of the fetus, which is within the normal range and does not need to worry or special intervention. However, if the ultrasound examination shows that the gestational week is one week greater than the actual gestational week, it is likely that the expected date of labor will be earlier, so it is important to pay attention to close pregnancy checkups, especially in the later stages of pregnancy, to regularly check and follow up on the development of the fetus, and to monitor whether there is any possibility of early delivery.
