Introduction to the characteristics of fetal heartbeat and fetal bud at several weeks

Every female friend who is pregnant is very concerned about the development of the fetus. Many friends want to know how many weeks after the fetal heart rate and embryo bud will appear. Many friends don’t understand this. The following article will explain to you how to judge and check the changes in the fetal heart rate and embryo bud.

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.

It is known that in the few weeks when there are fetal heartbeats and embryo buds, pregnant women should go to the hospital for regular health checks. They should regularly check whether the embryo is developing well and pay more attention to diet and sleep.
