The gestational sac is large and there is no fetal heart or fetal bud

The gestational sac is quite large and there is no fetal bud or fetal heart. Everyone has his or her own name for the gestational sac. Many people call it differently. The absence of a fetal bud or fetal heartbeat is very life-threatening for a woman, as it may be a sign that you may not have a baby. However, there are exceptions, and fetal arrest can still be saved. So is it possible that the gestational sac is very large but there is no embryo or fetal heartbeat?

After the fusion of sperm and egg to form sperm-egg union, the embryo implants and the sperm-egg union gradually disintegrates into a multicellular fetal sac. After more than thirty days of pregnancy, each primitive cell begins to divide and gradually forms a fetal bud and fetal heartbeat, which further develops into a fetal heartbeat. This is the whole process of a fetus being born.

Generally, the period from the third week of pregnancy to the first month of pregnancy is called the embryonic bud and fetal heart stage. At this time, blood data signals of heart beats can be seen during B-ultrasound or ultrasound examination, and further development will lead to the formation of a fetus.

For normal intrauterine pregnancy, B-ultrasound examination can usually show the fetal heartbeat and fetal heartbeat in the uterine cavity at 6-7 weeks of pregnancy. If there is still no embryonic bud, fetal heartbeat or fetal heartbeat after seven weeks of pregnancy, the expectant mother should consider the possibility of embryo termination and go to the hospital immediately to check the condition of the fetus.

Due to the growth and development of the test tube embryo, a gestational sac is produced on the 30th to 40th day of pregnancy, a fetal bud and fetal heartbeat are produced on the 40th to 50th day of pregnancy, and a fetal heartbeat is produced on the 50th to 60th day of pregnancy.

If you do an ultrasound examination around 40 days into the pregnancy, you can see the embryonic bud and fetal heart, which is 0.5-1 cm in size and shaped like a small seahorse. If the embryonic bud or fetal heartbeat is not detected, the expectant mother needs to pay attention.

However, there are also cases where some women with irregular menstrual cycles, late ovulation, or late embryo implantation have fetal buds and fetal heartbeats in their uterine cavity, and the timing of the fetal heartbeat will also be relatively delayed. It is recommended to observe for a week and then go to the hospital for a follow-up visit.

1. Chromosomal abnormality. Whether it is sperm or egg, as long as the sex chromosomes that carry genetic information are abnormal, even if the sperm and egg combine, the embryo will not develop normally.

2. Touched toxic substances. Hazardous substances include harmful compounds, inferior home decoration materials, etc. If pregnant women touch it, it will affect the growth and development of the embryo bud and fetal heart.

3. Exposure to direct radiation or a large amount of electromagnetic radiation. Pregnant mothers are exposed to X-rays without knowing it, which causes a lot of direct radiation exposure, and the growth and development of the embryo and fetal heart will also be affected.

4. Taking medicines that affect the growth and development of the embryo and fetal heart. Some early pregnancy reactions of pregnant women are very similar to cold symptoms, and their menstrual cycles are not very regular. Therefore, many people accidentally take cold remedies without knowing they are pregnant. In addition, there are also some patients with chronic diseases who, while taking medications for a long time, have accidental pregnancy without making good preparations for pregnancy. This is also a major factor affecting the incomplete development of the fetal bud and fetal heart.

5. Smoking or drinking. Smoking and drinking not only damage the female reproductive function, but also affect the quality of sperm, causing incomplete development of the embryo and heart, and ultimately causing the risk of fetal malformations.

6. The pregnant mother is infected with a virus. If a pregnant mother is infected with rubella, rubella virus, etc., the pathogens will indirectly infect the fetus, which may cause fetal malformations. High fever or viral infection may also cause uterine contraction and lead to miscarriage.

Everyone's situation is different. If the gestational sac is large and there is no fetal bud or fetal heartbeat, we must observe this situation carefully. Since there is no fetal bud or fetal heart, no matter how big the fetal sac is, it will be useless. We need to find out clearly what it is. In order to prevent this kind of situation from happening, we must take good care of ourselves.
