Patient's question:
Sure, I can help with that. However, you haven't provided any content to translate. Please provide the text you want to be translated into English.Doctor's answer:
Pre-marital and pre-pregnancy health checks are required, including teratogenic tests {rubella, toxoplasmosis, cytomegalovirus, human papillomavirus}. Folic acid should be taken starting three months before pregnancy. After becoming pregnant, immediately establish a prenatal health care card, undergo regular check-ups, and perform the Down syndrome screening between 14-20 weeks. B-ultrasound tests should be conducted before 28 weeks.
