The miracle of fetal bud and fetal heartbeat appears at the latest

The fetal bud and fetal heart are relatively important in the process of embryonic development. If the embryonic bud and fetal heart develop normally, the fetus will eventually develop into shape. Of course, the fetal heartbeat and fetal bud will appear at six weeks, but at the latest at eight weeks. If the fetal heartbeat and fetal teeth have not appeared during this period, it may be due to problems with the mother or the embryo itself!

1. When is the latest time for the embryo bud and fetal heartbeat to appear?

The earliest fetal heartbeat can be seen at six weeks, and the latest at eight weeks.

Pregnant mothers can usually see the gestational sac at 5 weeks of pregnancy, and the fetal bud and primitive heart tube beating at 6-7 weeks of pregnancy. Seeing a fetal heart beat confirms the diagnosis of early pregnancy and indicates a live fetus. If the embryo and fetal heartbeat are not seen after 7 weeks of pregnancy. It is necessary to determine whether the gestational age is consistent with the number of weeks of amenorrhea, dynamically observe blood HCG and progesterone, review the color Doppler ultrasound results, and judge whether the embryo is developing well based on the results.

Generally speaking, fetal heartbeat and fetal bud are important signs of the baby's healthy development. However, there are many times when the baby stops developing due to various reasons, and the fetal heartbeat and fetal bud will not appear. There are two manifestations of embryonic development cessation. The first is continuous vaginal bleeding. The second is that although there are no symptoms of vaginal bleeding, an ultrasound will reveal that the embryo has stopped developing and there is no embryonic bud or fetal heartbeat. In this case, most people don't feel anything, so it is recommended to go to the hospital for a check-up.

We know that when the fetus develops normally, it will have a fetal heart rate, which is the baby's heartbeat. The normal fetal heart rate is between 120 and 160. The fetal heartbeat can be heard at around 12 weeks, and later at 18 weeks. Many doctors now point out that if the fetal heart rate is lower than 140, then the baby is a boy, because generally speaking, a girl's heart rate is higher than that of a boy. However, such a test may not be completely accurate.

2. Characteristics of embryo bud

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.

3. Fetal heart rate characteristics

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.
