Patient's question:

Doctor:
Hello!
My wife is about 7 weeks pregnant. After the hospital examination today, the ultrasound description was as follows: the uterus is anteverted, slightly enlarged, with uniform wall echoes. A gestational sac echo was observed in the uterine cavity, with regular morphology and a size of 3621mm. A 10mm embryonic echo was seen inside it. However, no primitive cardiac pulsation was observed, but a yolk sac echo was visible. No abnormal echoes were found in the bilateral adnexal regions.
Could you please tell me if the baby can still be saved?

Doctor's answer:

Hello, don't worry, this situation is very rare. Since you are in the early stages of pregnancy, it is normal not to hear the fetal heartbeat. As long as there is no bleeding or abdominal pain, everything is fine. You can come back for a follow-up check-up in two weeks. Generally, doctors recommend that women with risk factors for prenatal examination should rest in bed and avoid sexual activity. Additionally, patients should also pay attention to a comfortable environment, which is beneficial for rest. Wishing the patient a healthy delivery.
