How big is the gestational sac visible to the embryo?

Patient's question:

No

Doctor's answer:

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