How long does it take to see the fetal heartbeat?

Many pregnant mothers go to the hospital to confirm the pregnancy and understand the fetal heart rate and development status after they learn that they are pregnant. At this time, many pregnant women find that their babies have no fetal heartbeat or fetal bud and are very anxious. So, when can we see the fetal heartbeat and fetal bud? Let's take a look at this issue below.

When can the fetal heartbeat and embryo be seen?

1. What is fetal heartbeat?

The fetal heartbeat is the heart rate of the fetus. As the saying goes, "the fetal heartbeat is the mother's heart, and the hearts are connected." The fetal heartbeat and fetal movement of the fetus can convey a lot of information to the pregnant mother. There may be a certain correlation between the fetal heartbeat and the pregnant woman's heart rate: if the pregnant woman's heartbeat is fast, the fetal heartbeat will also speed up; if the pregnant woman's heartbeat is slow, the fetal heartbeat will also slow down. It can reflect whether the fetus is healthy.

2. What is fetal heart rate monitoring?

Fetal heart monitoring is the general name for the fetal heartbeat, fetal movement and uterine contraction graph. It uses a fetal heart rate electronic electrocardiogram monitor to record the fetal heart rate curve and uterine contraction pressure waveform for clinical analysis. It is an important test method to accurately assess the intrauterine condition of the fetus. It uses microwave technology and is harmless to the child. You only need to buy a fetal heart rate monitor. Especially after the fourth month of pregnancy, it is important to monitor the baby yourself. The interesting thing is that sometimes you can even hear the baby hiccuping.

3. Contents of Fetal Heart Monitoring Examination

Fetal heart rate monitoring is regulated by the central nervous system and sympathetic nervous system. The curve of the monitoring graph produced by recording the changes in the fetal heartbeat in an instant through data signals can be used to understand the response of the fetal heartbeat when the baby moves and the uterus contracts, so as to infer whether the fetus in the uterine cavity is short of oxygen.

4. Safety Factor of Fetal Heart Monitoring

Fetal heart rate monitoring is to use the principle of ultrasound to detect the condition of the fetus in the uterine cavity, which is safe for the fetus.

5. When should fetal heart rate monitoring be started?

Generally, self-monitoring cannot be performed before 15 weeks of pregnancy. For pregnant women between 15 and 28 weeks of gestation, it is safe to measure three times a day for one minute each time. For pregnant women after 28 weeks of pregnancy, the fetus has completely split and the monitoring time and frequency can be extended. For high-risk pregnant women after 35 weeks of pregnancy (for example, pregnant women with combined pregnancy-induced hypertension, hyperthyroidism, etc.), they should be hospitalized and use a fetal heart rate monitor to continuously monitor the fetal heartbeat. If necessary, long-term (more than 1 hour) continuous monitoring can be carried out.

Now everyone should have a deep understanding of how long it takes for fetal heartbeat and fetal bud to appear during pregnancy. I hope that pregnant women can go for more physical examinations. This will also take into account the health of the pregnant woman and the baby in her belly, and the quality of the baby born will be much higher. If you find that the fetal heartbeat in your belly is abnormal, you should pay attention to it and it is best to seek treatment in a regular hospital.

What are the fetal growth and development indicators?

4 weeks of pregnancy: The fetus is only 0.2 cm. The amniotic cavity is formed just after the sperm and egg combine and the embryo implants, and its volume is not large. Ultrasound cannot clearly show signs of pregnancy.

5 weeks of pregnancy: The fetus grows to 0.4 cm and enters the test tube embryo stage. The amniotic cavity expands, initial cardiovascular and cerebrovascular diseases appear, and heart beats may be present. B-ultrasound can show a small gestational sac, which occupies less than 1/4 of the uterine cavity, or the embryonic bud and fetal heartbeat can be seen from it.

6 weeks of pregnancy: The baby grows to 0.85 cm, the baby's head, brain alveoli, frontal organs, respiratory, digestive, neural and other organs are divided, the gestational sac is clearly visible on B-ultrasound, and the fetal bud, fetal heart rate and fetal heart rate are seen.

7 weeks of pregnancy: The fetus grows to 1.33 cm, the test tube embryo has a human prototype, the body segments have all divided, the limbs have separated, and the various systems are further developing. B-ultrasound clearly shows the embryo, fetal heart rate and fetal heart rate. The gestational sac occupies about 1/3 of the uterine cavity.

8 weeks of pregnancy: The fetus grows to 1.66 cm, the fetal shape is fixed, the fetal head, body and limbs can be separated, and the fetal head is larger than the body. B-ultrasound shows that the gestational sac occupies about 1/2 of the vagina, the shape of the fetus and the fetal movement are clearly visible, and the yolk sac can be seen.

9 weeks of pregnancy: The fetus grows to 2.15 cm, the fetal head is larger than the embryo, the main manifestations of various parts are clearer, the head begins to thicken, and the embryo begins to grow. B-ultrasound shows that the gestational sac is almost filling the uterine cavity, the outline of the fetus is clearer, and the embryo has just begun to appear.

10th week of pregnancy: The fetus grows to 2.83 cm, the fetus's internal organs have been formed, and the embryonic prototype has been formed. B-ultrasound showed that the gestational sac had begun to shrink, and the crescent-shaped embryo was visible, and the fetus was active in the amniotic fluid of the pregnant woman.

11 weeks of pregnancy: The baby grows to 3.62 cm, the baby's internal organs continue to grow and develop, and the embryo grows and develops. B-ultrasound showed that the gestational sac had completely disappeared and the embryo was clearly visible.

12 weeks of pregnancy: The fetus grows to 4.58 cm, the reproductive organs are basically developed, any deformities may be manifested, and the head thickens and becomes more complete. The skull halo is clear, the biparietal diameter of the fetus can be measured, obvious deformities can be diagnosed, and the internal organs tend to be healthy.
