Eight weeks pregnant, no fetal heart, germ.

It may be abnormal for embryo bud to be pregnant for 8 weeks without a fetal heart. According to the development of embryo, embryo sac is formed in 30-40 days, embryo bud is formed in 40-50 days, and fetal heart is formed in 50-60 days. So generally speaking, you can see the fetal sac around 5 weeks of pregnancy, and you can see the embryo and fetal heartbeat at 6 weeks of pregnancy. However, if there is no fetal heart embryo in the eighth week of pregnancy, it may be abnormal, and it is likely that there is a problem with embryo development. Pregnant women should check again after one week to confirm.

The reason that affects embryo development is that there is no fetal heart germ after 8 weeks of pregnancy. It is very likely that there is something wrong with embryo development. So, what are the reasons that affect embryo development? 1. Genetic factors: If there are chromosomal abnormalities or genetic defects, there are common chromosomal abnormalities of sperm or eggs. Maternal factors: such as poor health or disease, cervical atresia, luteal insufficiency, endometriosis, immune factors, diabetes, hyperthyroidism, etc. Male factors: such as a large number of bacteria in semen, high sperm deformity rate.

2, insufficient hormone secretion is difficult to support embryonic development and leads to death. Abnormal uterine cavity prevents embryo growth. Virus infection during pregnancy, exposure to radioactive substances, toxic chemicals, taking prohibited drugs during pregnancy, high temperature, microwave, noise, excessive stimulation, etc.

What are the symptoms of embryo abortion?

Embryo bud, there is no fetal heart after 8 weeks of pregnancy, and it is very likely that the embryo will abort. What are the symptoms of embryo abortion? 1, the pregnancy reaction disappeared. If the embryo is stopped after 8 weeks of pregnancy, all pregnant reactions of pregnant women will gradually disappear. First, early pregnancy reactions such as nausea and vomiting no longer disappear, and then the feeling of breast fullness weakens. At this time, we must pay attention and be vigilant.

2, vaginal bleeding, abdominal pain, pregnant women who are pregnant for 8 weeks, after abortion, after the early pregnancy reaction disappears, there will be symptoms of vaginal bleeding, generally dark red bloody leucorrhea. There are also some pregnant women with lower abdominal pain, which is likely to be a harbinger of fetal stop development and should be checked in the hospital immediately. The diagnostic criteria of B-mode ultrasound for fetal arrest are: embryo development ≥6 weeks without gestational sac, or deformation and shrinkage although there is gestational sac; When the gestational sac is ≥4cm but the embryo is not visible, and the head and arm length of the embryo is ≥ 1.5cm but there is no fetal heartbeat, it can be judged that the embryo is abnormal. Pregnant women have different symptoms of miscarriage. Some even have no symptoms at all, direct abdominal pain and then abortion, or routine B-ultrasound examination found no symptoms after abortion. If it is confirmed that a pregnant woman has a miscarriage, some people can have a complete abortion without curettage, but there are still many pregnant women who need curettage because the embryo cannot flow out of the body after abortion.
