What is the reason for the absence of embryo in early intrauterine pregnancy?

Now let us introduce another problem that women may encounter during pregnancy - intrauterine pregnancy without the presence of embryo. We all know that various problems will arise when a woman is pregnant, so pregnancy care is very important. Next, let’s talk about the concepts of early pregnancy and embryo, as well as the reasons why no embryo is seen in early intrauterine pregnancy.

Early pregnancy:

Early pregnancy refers to pregnancy within 12 weeks of pregnancy. The embryo undergoes dramatic changes in development at this time. About half of women will experience nausea, vomiting, salivation, preference for sour food, aversion to greasy food, gastrointestinal bloating accompanied by a burning sensation, upper abdominal fullness, constipation and other phenomena in the early pregnancy period about 6 weeks after menstruation. These phenomena are called early pregnancy reactions. This early pregnancy reaction disappears on its own in about 12 weeks.

Germ:

During the development of the embryo, the gestational sac is formed in 30-40 days, the embryo bud is formed in 40-50 days, and the fetal heart is formed in 50-60 days. Generally, under normal development, the embryo bud and cardiovascular fluctuations can be seen around 7 to 8 weeks of pregnancy.

reason:

1. The number of days is too short or fertilization is late, and no embryo has appeared in the gestational sac: Generally, the embryo will be found during B-ultrasound examination around 8 weeks of pregnancy. The gestational sac is just the primitive fertilized embryo. The appearance of the embryo and fetal blood vessel pulsation is the real fetus! First of all, you need to look at your menstrual cycle. Different menstrual cycles will lead to different early pregnancy cycles, which means that the results of determining the first few weeks may be different. If it is before 8 weeks, it is not surprising that the gestational sac is too small to be seen.

2. Arrest of pregnancy: If there is no embryo at 8 weeks, you should consider whether the embryo has stopped developing. Fetal growth retardation cannot be kept, otherwise the dead fetus remaining in the uterine cavity may cause infection, etc. It is recommended to handle it under the guidance of the attending physician, pay attention to finding out the cause of fetal growth retardation, and consider pregnancy after timely treatment.

Through the introduction of the above article, we understand the reasons why no embryo is seen in early intrauterine pregnancy. The process of pregnancy is a process full of variables. The baby develops from a fertilized egg, from a tiny cell into a child with a nose, eyes, hands and feet. There are many uncontrollable factors in this process. Therefore, we need to go for regular prenatal check-ups to ensure the safety of the mother and fetus.
