How to perceive whether the baby is developing normally during pregnancy

Patient's question:

No

Doctor's answer:

At weeks 15-20 of pregnancy, a Down syndrome screening is performed to assess the intellectual development of the fetus. Between weeks 22-26, a 4D ultrasound is conducted to check for major fetal abnormalities and the development of key organs. If there are no abnormalities in the prenatal check-ups, it indicates that the fetus is developing well. Wishing you a good pregnancy.
