Sure, I can help with that. Please provide the content you want to be translated into English.Doctor's answer:
Hello, the Down syndrome screening is usually done between weeks 14-19 of pregnancy. At week 20, you should choose a suitable hospital to establish a prenatal checkup card and regularly undergo prenatal examinations. (Some may start establishing the prenatal checkup card and regular checkups as early as 3 months into pregnancy.)
