What is the method to check fetal heart rate and embryo during pregnancy?

During the prenatal checkup, pregnant women should not only check the normal dimensions of their abdomen, but also determine whether there are signs of miscarriage, whether the body's secretions are normal, whether the chromosomes are normal, and most importantly, do a good job of pregnancy checkups, fetal heart rate and fetal buds to prevent abnormal changes in the fetal buds, and the body should also undergo relevant testing.

Abnormal embryo

Embryonic factors

1. Abnormal embryonic development is the most common cause of early miscarriage, and miscarriage caused by chromosomal abnormalities accounts for about 50~60%.

2. Placental abnormalities: Due to incomplete development of the trophoblast, degeneration of the placental villi, or the placenta being attached too low, fetal-placental circulation may be impaired, leading to miscarriage.

Maternal factors

1. Acute infectious diseases, which may cause fetal death due to pathogens or toxins invading through the placenta, or cause uterine contractions and miscarriage due to high fever or poisoning;

2. Severe anemia or heart failure, resulting in fetal death due to lack of oxygen;

3. Endocrine disorders, such as corpus luteum insufficiency, lead to decidua dysplasia and affect the development of fertilized eggs;

4. Uterine hypoplasia, uterine fibroids or deformities can also hinder embryonic development;

5. Sometimes, the relaxation of the internal cervix can cause the inability to withstand the increased pressure of the fetal sac, leading to late miscarriage;

6. Strong mental stimulation, trauma or sexual intercourse can also cause miscarriage, but the inducing factors are often mainly caused by defects in the embryo itself.
