A CRL of 60mm and a BPD of 20mm are normal. A CRL of 60 mm corresponds to 12.7 weeks and a BPD of 20 mm corresponds to more than 13 weeks, which is normal for a pregnancy of about 12 weeks. Fetal development should be evaluated during pregnancy based on ultrasound measurements. Any fetal growth restriction should be treated promptly. During pregnancy, regular and standardized obstetric examinations should be conducted under the guidance of obstetricians, and if abnormalities are found during the examination, obstetricians should be consulted promptly. In addition, you should pay attention to balanced nutrition during pregnancy, ensure the intake of protein and calcium, and reasonably control the weight during pregnancy under the guidance of obstetricians.
