Premonition of fetal arrest in four months of pregnancy

Four months of pregnancy is the second trimester. At this time, it does not mean that the child is necessarily in a stable condition. As long as the child has not been born, the expectant mother should take precautions to prevent accidents that may easily cause miscarriage and affect the safety of the child. So, what are the symptoms of fetal arrest at four months of pregnancy? Will fetal arrest continue at four months of pregnancy?

What are the symptoms of fetal arrest in the fourth month of pregnancy?

If the embryo stops developing, all pregnancy reactions of the pregnant mother will gradually disappear. First of all, you will no longer have nausea, vomiting and other early pregnancy reactions, and the feeling of breast swelling will also gradually weaken. There is also vaginal bleeding afterwards, often with dark red bloody leucorrhea. Eventually, you may experience lower abdominal distension and pain, and the test tube embryo may be expelled. The above symptoms vary from person to person. Some people may not even have any symptoms, but may experience abdominal pain immediately, followed by miscarriage, or the embryo may stop developing and then be discovered through basic B-ultrasound examination without any symptoms.

Most pregnant women have no obvious symptoms after the fetus stops growing and developing. Some pregnant women may have spotting, but generally have no abdominal pain, which is different from threatened abortion.

Patients with a history of amenorrhea should undergo B-ultrasound examination in the early stages of pregnancy, regardless of whether they have spotting or not, to avoid misdiagnosis of embryonic arrest. B-ultrasound can be used to check the test tube embryo and the baby's development. If there is no gestational sac at 6 weeks, or there is a gestational sac but it is deformed and wrinkled, when the gestational sac is 4cm but no fetal bud or fetal heartbeat can be seen, or the head and arm length of the fetal bud or fetal heartbeat is 1.5cm but there is no fetal heartbeat, it can be judged that there is something wrong with the development of the test tube embryo or the baby. The latter three conditions can be diagnosed as embryonic arrest. In addition, blood measurements are also helpful in confirming the cessation of embryonic development. For example, if at 5 weeks, the blood level is 100 IU/L; at 6 weeks, the blood level is 2000 IU/L, this indicates that the metabolism of chorionic gonadotropin is insufficient. If the value is no longer increasing through dynamic observation, it can be judged that the villous epithelial cells are declining and the test tube embryo is abnormal.

Causes of fetal stillbirth in early pregnancy

Early pregnancy is a very risky period. At this time, the test tube embryo develops in the uterus, but the embryonic development process is not stable, so in the early stages of pregnancy, the fetus is very likely to have some problems. If fetal stillbirth occurs in early pregnancy, there are many different reasons for fetal stillbirth. What are the actual reasons?

1. If the mother has a disease, it will immediately affect the normal growth and development of the fetus. The growth and development of the fetus is generally determined by the supply and demand balance of the mother. At this time, all elements of the body are transmitted to the fetus and affect the fetus. If a pregnant woman has diabetes and high blood pressure during pregnancy, it is possible to hinder the input of CO2 and nutrients to the fetus, which can easily lead to fetal malnutrition and lack of oxygen, leading to fetal death.

2. The formation and development of the fetus are affected by many factors. Not only the mother's physical and mental health will affect the fetus, but the fetus will also be affected by sex chromosomes. If there is an abnormality in the sex chromosomes and congenital malformations occur, it can easily lead to the death of the fetus. If the fetus is infected by viruses or bacteria, or even the umbilical cord slips, the fetus may die.

3. The embryo and the natural environment affect the physical and mental health, growth and development of the fetus. If the embryo experiences premature abruption, it will immediately cause fetal death. If it is hit by external factors, it is likely to cause placental abruption. If the placenta is not functioning properly, it will immediately hinder the normal growth and development of the fetus, and it is easy to cause fetal death. Placenta previa can also cause fetal death. There are also certain risks in overdue pregnancy, because the pregnancy period is too long, it may cause fetal distress and death.
