Patient's question:
No.Doctor's answer:
Hello, the traditional method of estimating fetal gestational age based on the last menstrual period is suitable for women with cycles of about 30 days. If the cycle is longer, the date of conception and the last menstrual period will differ by a longer period of time, resulting in the ultrasound showing a gestational age smaller than that calculated based on the last menstrual period. As long as prenatal check-ups are conducted on schedule and the fetus is normal, there is no need to be too concerned about the gestational age.
