Is the Yinfang check earlier than the B check for gestational sac?

Patient's question:

No

Doctor's answer:

If vaginal ultrasound is performed in the early stages of pregnancy, it may cause a miscarriage. It is necessary to drink water and hold urine for abdominal ultrasound to confirm whether it is an intrauterine pregnancy. It is recommended to have regular prenatal examinations, get adequate rest, maintain a balanced diet with sufficient nutrition, and eat more fish, eggs, vegetables, and fruits. Wishing you a smooth pregnancy and good health!
