In the early stages of pregnancy, only the gestational sac is visible without the fetal bud or primitive heartbeat, how to respond

Patient's question:

No

Doctor's answer:

Hello, the gestational sac is still relatively small. Based on the size of the gestational sac, it is normal not to see a fetal pole and heartbeat. The current gestational sac is quite small, which could be due to late implantation or poor fetal development.
