After the early pregnancy stops, the gestational sac will not grow in most cases, but due to the different hormone levels in each woman’s body, some women may continue to grow the phenomenon of the gestational sac, which is called the empty sac, and can not continue the pregnancy. Whether or not the gestational sac will grow after early pregnancy arrest varies from person to person, regardless of whether or not the gestational sac grows, as long as the fetal arrest needs to terminate the pregnancy in a timely manner. There are many causes of fetal arrest, such as chromosomal abnormalities, environmental factors, immune factors, etc.. After discovering fetal arrest, it is recommended to go to a higher level hospital for examination and diagnosis, and terminate the pregnancy promptly after diagnosis to avoid increasing the chance of hemorrhage. After removing the arrested embryo, it is also necessary to regularly review the uterus and human chorionic gonadotropin status.
