A large gestational sac with small embryonic buds indicates that the fetus is not developing very well. The embryonic buds of the fetus can provide nutrients to the gestational sac. If the gestational sac is large and the embryo is small, it means that there is underdevelopment of the fetus, but it is also possible that the fetus has stopped growing, which is also related to the insufficient nutritional intake of the mother. After the emergence of large gestational sacs and small embryonic buds, you can first observe at home for a few days, during this period, pay attention to strengthen nutrition, and then go to the hospital after a week to review, to see whether the embryo is growing, and if there is a situation in which the fetus stops growing, then we should terminate the pregnancy in a timely manner.
