8 weeks of pregnancy with embryo but no fetal heartbeat

Every pregnant woman is very afraid of the problem of fetal arrest. The occurrence of fetal arrest will not only cause great loss of qi and blood to the pregnant woman's body, but also cause great harm to the pregnant woman's mind. The early stages of pregnancy are a very critical period, because during this period the fetus is weak and problems can easily occur. Therefore, pregnant women in the early stages of pregnancy must go to the hospital for prenatal checkups regularly. However, what is going on when a prenatal checkup in the eighth week of pregnancy finds that there is a fetal bud but no fetal heartbeat?

I am 8 weeks pregnant and there is a fetal bud but no fetal heartbeat. What's going on?

Generally, fetal heart activity can be checked through B-ultrasound at eight weeks of pregnancy. If no heart activity is found, it is recommended to observe for about another week. If there is still no heart activity, it may indicate that the embryo has stopped developing. Normally, during the 42nd to 56th day of pregnancy, a color Doppler ultrasound examination should be able to show the gestational sac and fetal heartbeat. Guidance: If you cannot see it at this time, it is not normal. However, if ovulation is late, it is possible that you can see it late. You can wait another ten days to half a month and then check again. It is recommended that you take progesterone for pregnancy preservation under the guidance of a doctor, and then recheck the B-ultrasound after one week to observe the development of the fetus. Pay attention to rest and avoid fatigue. I suggest that since your progesterone level has dropped and there has been no fetal heartbeat for two months, you may be considering developmental delay or embryonic development arrest. You should observe for a few more days. The size of the gestational sac is equivalent to six to seven weeks of amenorrhea. If there are no bleeding or other signs of threatened abortion, you can check again after a week. If there is still no fetal heartbeat by then, it means fetal arrest and you can only have an artificial abortion.

What to do if the embryo stops developing

There are many reasons why the embryo stops developing. Common reasons include genetics, infection, immunity, exposure to radioactive substances or toxic chemicals, drugs that are contraindicated for pregnant women, high temperature, excessive stimulation, etc. The embryo itself has defects or stops developing due to adverse factors during the development process. There are also problems with infection, immunity, etc. These diseases include diabetes, hyperthyroidism, etc. You should not be in a hurry to get pregnant again. Generally, you should consider having a child after 3 months. Instead, you should look for the cause of the disease, the four eugenics items, antisperm antibodies, antiphospholipid antibodies, anti-chorionic gonadotropin antibodies, ureaplasma urealyticum, Chlamydia trachomatis, sperm quality, egg development, etc.

If fetal arrest occurs, the mother's body will undergo a series of changes to facilitate its expulsion. First, the levels of estrogen and progesterone decrease, the body produces an immune rejection effect on the embryo, and blood vessels between the mother and the embryo form blood clots and break off, which may cause vaginal bleeding in the process. Early pregnancy reactions may be alleviated after embryonic arrest, but early pregnancy reactions themselves vary from individual to individual, so early pregnancy reactions cannot be used to judge the development of the embryo. Most pregnant women have no obvious symptoms after the fetus stops developing, and a clear diagnosis is required through hormone testing combined with early pregnancy ultrasound testing. It is recommended to go to a regular reproductive hospital for detailed examination and symptomatic treatment based on the examination results.
