What does it mean to have a gestational sac with a blastocyst but no fetal heartbeat?

Patient's question:

No

Doctor's answer:

According to your description, the fetal development is still very healthy. The gestational sac is developing well. The absence of fetal heartbeat and fetal bud is because it's too early and they haven't developed yet, so they are not visible. As the gestational age increases, they will naturally become visible. Pay attention to the nutrition of the pregnant woman.
