Is an ultrasound check accurate for detecting a germ?

Patient's question:

No

Doctor's answer:

Generally, it is necessary to wait at least 6 weeks to see the yolk sac. It is recommended that you postpone the re-examination by one or two weeks to see if it is visible. If you have not taken highly toxic drugs during pregnancy, there is no need to worry. It is better to postpone the re-examination by two weeks.
