Is it normal to have no fetal heartbeat or embryo at 50 days of pregnancy?

During pregnancy, most pregnant women are happy and excited because they are about to become mothers. Some pregnant women are not in a good mood, probably because the reaction of pregnancy is very strong. Pregnant women need to go to the hospital for pregnancy check-ups every month. The baby's development standards are different every month. Is it normal to have no embryonic bud or fetal heartbeat at 50 days of pregnancy?

Is it normal to have no fetal heartbeat at 50 days of pregnancy?

The main problem is that there is no test tube embryo but a gestational sac in the uterus.

At 7 weeks, B-ultrasound can clearly show the embryo, fetal heart and fetal heart rate. Whether the menstrual period is normal or the ovulation is delayed, resulting in late sperm and egg implantation, so the gestational age does not match the pregnancy week. The heartbeat cannot be seen temporarily. Wait a week for B-ultrasound to see. If there is indeed no fetal heartbeat, surgery should be performed as soon as possible to avoid fetal death in the uterine cavity and affect the health of the pregnant woman.

It mainly depends on your menstrual cycle. If your menstrual period is long, it is normal at the moment; if your menstruation is normal, it may be an agenesis. It is recommended to observe for 10 to 15 days. If a test tube embryo is found, it is normal.

Under normal circumstances, the gestational sac can be observed around 6 weeks of pregnancy, and the initial primitive heart tube beat and fetal heartbeat can be observed only at 8 weeks of pregnancy. Now it is not possible to observe whether it is caused by the short pregnancy period. It is recommended that you release the pressure, observe again, and have a follow-up ultrasound after 10-14 days to understand the status of the embryonic development process.

This is normal. There is no fetal heartbeat at 50 days. If there has been no vaginal bleeding and severe abdominal pain before, don't worry. Seeing the fetal heartbeat at 50 days of pregnancy is just a standard value, because your actual pregnancy time and the number of days of pregnancy used for calculation are different.

Generally, the primitive heart beat can be seen through B-ultrasound at about 8 weeks of pregnancy, the fetal bud and fetal heart rate can be seen at 6-7 weeks, and the fetal bud and fetal heart rate can be seen at 6-7 weeks. If the fetal bud and fetal heart rate are not seen, it may be due to late fertilization or certain errors in B-ultrasound. You don't need to be too anxious. It is recommended to follow the doctor's advice and go to a reliable hospital's gynecology department for a follow-up visit.

Size of embryo bud and fetal heart:

Normally, the fetal bud and fetal heart rate can be seen by B-ultrasound at 6-7 weeks of pregnancy.

4 weeks: 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: 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: The fetus grows to 0.85 cm, and the head, brain alveoli, frontal organs, respiratory, digestive, and nervous organs of the fetus are divided. The gestational sac is clearly visible on B-ultrasound, and the fetal bud, fetal heart rate, and fetal heart rate are also seen.

7 weeks: The fetus grows to 1.33 cm. The embryo has a human prototype. The body segments have been completely divided, the limbs have been separated, and the various systems have further developed. 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: 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 uterine cavity, the shape of the fetus and the fetal movement are clearly visible, and the yolk sac can be seen.

9 weeks: 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.

10 weeks: The fetus grows to 2.83 cm, the fetus's internal organs have been formed, and the embryonic prototype is 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.
