Can you hear the fetal heartbeat at 40 days of pregnancy?

Patient's question:

No

Doctor's answer:

Generally, fetal heartbeat can be detected by ultrasound at 7-8 weeks of pregnancy. If it is a miscarriage, it may occur naturally, or there may be intrauterine fetal demise without excluding the possibility of a miscarriage due to fibroids. However, both of these cases usually involve symptoms such as bleeding and abdominal pain, as well as vaginal bleeding. It is recommended to follow up in a few days for a clear diagnosis.
