Pregnant women with a second child should pay attention to what?

Patient's question:

No

Doctor's answer:

For a healthy baby, please remember to do pre-pregnancy tests! Receiving tests and consultations before pregnancy not only allows expectant mothers to carry the next generation in the healthiest condition but also helps to know in advance whether special prenatal fetal diagnosis is needed. Pre-pregnancy eugenics tests are just like our health checks, with varying numbers of items.
