Symptoms of yolk sac without embryo bud and fetal heartbeat

In today's increasingly developed society, many expectant mothers are no longer like pregnant women in the past. There are now many instruments that can detect the current status of the fetus in the mother's belly. However, many expectant mothers may have encountered such a situation that there is a yolk sac but no embryo or fetal heart. Let us take a look at the specific symptoms below.

Symptoms:

Embryo characteristics

The first month of pregnancy is the embryonic stage, during which the new life grows the fastest in its life. The sperm and egg combine at the end of the second week of pregnancy. About 4 days after fertilization, the sperm and egg, which have split into cell clusters, travel along the fallopian tube to the uterus. In the third week, the cell mass sheds its outer membrane in preparation for implantation. By the fourth week, the blastocyst has been firmly implanted in the uterus. During this period, the prototypes of the fetal nervous system and circulatory organs (the basic tissues) have almost appeared, and the liver begins to develop significantly from this period; the prototypes of the eyes and nose have not yet been generated, but the prototypes of the mouth and chin can be seen; the umbilical cord connected to the mother also begins to develop from this period.

Fetal heart rate

The fetal heart rate is the heartbeat of the fetus, which can usually be heard in the abdomen with a normal stethoscope between 17 and 20 weeks. The fetal heart rate is 120-160 beats/minute, sometimes even faster and less regular. It becomes more regular towards the end of pregnancy. Sometimes there may be a brief pause in the heartbeat, or the heart rate may reach 180 beats per minute, which is normal. However, if this phenomenon occurs frequently or for a long time, you should seek medical attention in time.

Normal range

The normal fetal heart rate is regular and strong, like the ticking of a clock, at 120-160 beats/minute. If it is 120 beats/minute or 160 beats/minute, you can listen to it again at intervals of 10-20 minutes. If it is still abnormal, it indicates fetal intrauterine hypoxia. If the fetal heart rate is within the abnormal range and is accompanied by irregular fetal heart rhythm, it indicates that the fetal hypoxia is more serious.

Maternal factors

1. 1. Acute infectious diseases can cause fetal death due to pathogens or toxins invading through the placenta, or cause uterine contractions and miscarriage due to high fever or poisoning; 2. Severe anemia or heart failure can cause fetal hypoxia and death; 3. Endocrine disorders, such as corpus luteum insufficiency, which can lead to decidua hypoplasia and affect the development of fertilized eggs; 4. Uterine hypoplasia, uterine fibroids or malformations can also hinder embryonic development; 5. Sometimes, due to relaxation of the internal cervical os, it cannot withstand the increased pressure of the fetal gestational sac, resulting in late miscarriage; 6. Strong mental stimulation, trauma or sexual intercourse can also cause miscarriage, but the frequent inducing factors are mainly caused by defects in the embryo itself.

The above article describes in detail the symptoms of having a yolk sac but no embryonic bud or fetal heart. I believe everyone has some understanding of it. In normal times, you should pay more attention to this aspect and go to the hospital for gynecological examinations and prenatal examinations in time to know the condition of the fetus.
