How long after the gestational sac implants does the fetal heartbeat appear?

Patient's question:

No

Doctor's answer:

Hello, if your menstrual cycle is long, ovulation is delayed, and implantation occurs late, it is normal not to see a fetal heartbeat or fetal bud. As long as you do not experience symptoms such as abdominal pain or bleeding, and have no discomfort, there is no major concern. It is recommended that you check again in a few days to see if there is a fetal heartbeat. Wishing you health.
