How many days should we check the fetal heart rate and fetal embryo?

During pregnancy, there will be many abnormalities in the fetal heart rate and fetal buds. For example, there will be problems with the embryo's chromosomes, which may lead to abnormal embryonic development and severe cases may lead to miscarriage. In addition, there are many maternal factors that can affect the fetal heart rate and fetal buds. For example, some women suffer from acute infectious diseases or endocrine disorders, etc., which may affect the development of the fertilized egg. So, under normal circumstances, how long does it take to detect the fetal heart rate and fetal buds?

How many days should we check the fetal heart rate and fetal embryo?

For many expectant mothers, the growth of the baby in the belly is what they are most concerned about. Many expectant mothers will go to the hospital for B-ultrasound examination after a period of pregnancy. So, how long does it take for expectant mothers to be able to detect the fetal heartbeat and fetal bud? Let’s learn more about it in detail with the editor!

How long does it take to detect fetal heart rate and embryo?

Generally speaking, the fetal heartbeat will be detected during B-ultrasound at around 8-10 weeks, but if you do B-ultrasound too early, it will not be easy to see the gestational sac because it is too small. Under normal circumstances, it is easy to see at 8-10 weeks of pregnancy. In addition, if the B-ultrasound is done too early, the fragile and newly formed embryo will theoretically be shaken, which is not conducive to embryonic development. It is best to avoid doing B-ultrasound too early.

Characteristics of fetal heart and fetal bud

Embryo

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 regular 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.

Expectant mothers are very concerned about the condition of the baby in their belly, but they must not be too hasty and blindly conduct various examinations to avoid damaging the health of the baby in their belly. If expectant mothers want to understand clearly, it is best to conduct the examination under the guidance of a doctor.
