At 8 months of pregnancy, the fetus has no fetal heartbeat. What could be the reason?

Patient's question:

No

Doctor's answer:

Hello, the yolk sac usually appears around week 5 of pregnancy, and the embryo with a heartbeat typically appears between weeks 6-8. If it hasn't appeared by week 10, it's important to consider the possibility of fetal demise, and pregnancy termination can be considered in a timely manner. There are many causes of fetal demise, such as genetic factors, immune issues, medication, infection, and more. It's best to undergo testing before pregnancy.
