Does the Down syndrome screening still need to continue after passing 20 weeks?

Patient's question:

I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried it might affect fertility, and I also feel extremely cold and afraid of the cold. May I ask if the Down syndrome screening is still necessary after passing 20 weeks?

Doctor's answer:

The Down syndrome screening is used to identify children with Down syndrome, which is a common congenital fetal malformation often seen in clinical practice. Generally, we recommend performing the test between the 14th and 20th weeks of pregnancy. It is advised to rest more, maintain a light and warm diet, eat more fruits and vegetables, and keep a positive mindset. You can take pregnancy tonics and receive progesterone injections. It is best to have a follow-up ultrasound after one week of maintaining the pregnancy to check the fetus's condition. Wishing you good health.
