Gestational sac 30mm, no embryo

Girls are all pregnant. Pregnancy is very difficult. It is not easy to understand if you have not really experienced it. You must be cautious when you are pregnant and pay attention to your diet and medication. At this time, there will be many unknown conditions waiting for expectant mothers, such as why the fetal sac is 30mm and there is no fetal bud or fetal heartbeat? Let's have a simple understanding and understanding of this issue. I hope the following points will be helpful to everyone!

The embryonic bud is an important indicator to determine whether the fetus in early pregnancy is growing and developing normally. If the gestational sac is 30 mm and no embryo is seen on B-ultrasound, the possibility of fetal demise should be considered.

1. The embryo bud is very small: Because many pregnant women have too long menstrual cycles before pregnancy, menstrual disorders and other factors, which may lead to errors in the number of days of pregnancy. Some pregnant women have amenorrhea for 49 days, but that does not mean that the pregnancy is a full 49 days. Therefore, if no embryo is found during B-ultrasound at 7 weeks of pregnancy, it may be that the pregnancy is too short and the embryo has not yet grown. Pregnant women do not need to worry too much and can come back for a follow-up checkup after a week.

2. Fetal growth retardation: If the test tube embryo does not grow and develop, B-ultrasound will show that there is a gestational sac but no fetal heart or fetal bud, and it will be accompanied by a small amount of vaginal bleeding. Therefore, if no embryo is seen during pregnancy, it may be a sign that the test tube embryo has already stopped growing and developing and needs to be aborted. The main reason for the cessation of embryonic development is the chromosomal abnormality of sperm and egg fusion, which is largely due to natural replacement. Pregnant women don't need to be too sad, they should take the initiative to do a good job of examination and prepare for the next pregnancy.

Ultrasound examination showed a gestational sac of 30mm, but no embryonic bud or fetal heartbeat, indicating that the fetus has already stopped growing and developing and requires a uterine curettage.

The presence of a gestational sac but no embryonic bud is considered to be caused by incomplete development of the fetus, and the doctor recommends a sex chromosome test. If the embryo stops developing, the pregnancy must be terminated. There are many reasons for fetal growth retardation, including immune system disease factors, genetic factors, infectious factors, endocrine factors, anatomical factors, etc. Generally, fetal growth retardation occurs during the first pregnancy. If the cause cannot be found, it is useless to rely blindly on fetal preservation during subsequent pregnancies.
