Is it possible to be 10 weeks pregnant with no yolk sac and embryo?

It is not possible to be 10 weeks pregnant with no yolk sac and embryo.

The yolk sac is present from the early stages of embryonic development and is essential for the nourishment and sustenance of the growing embryo. It provides nutrients and oxygen to the embryo before the placenta develops and takes over this role.

The absence of both the yolk sac and embryo at 10 weeks of pregnancy would indicate that the pregnancy is non-viable and has unfortunately ended in miscarriage. In such cases, it is recommended to consult with a healthcare provider for further evaluation and support.
