Six months of pregnancy

Under normal circumstances, a woman's pregnancy is relatively stable for six months, but some pathological factors cannot be ruled out, which may cause danger to a woman during pregnancy, such as fetal growth retardation. The problem of fetal growth retardation is something that many women are very worried about. There are many reasons for fetal growth retardation. Generally, women will have symptoms when fetal growth retardation occurs, so you should pay attention to protection during pregnancy. So what are the signs of miscarriage during the sixth month of pregnancy?

1. If intrauterine fetal death occurs at 6 months of pregnancy, that is, 24 weeks of pregnancy, it is caused by pathological factors. Acute or chronic hypoxia of the fetus in the uterine cavity endangers his health and life and can cause fetal distress or even intrauterine fetal death. The causes of acute or chronic hypoxia are related to insufficient maternal blood and oxygen content, blood oxygen transport and exchange disorders between the mother and the fetus, and factors of the fetus itself. Acute fetal hypoxia is often caused by uterine and placental blood circulation disorders, obstructed gas exchange, or umbilical cord blood circulation disorders. Common causes include placenta previa, placental abruption and promotion of uterine contraction, which are related to improper use of oxytocin, overdose of anesthetic or sedative drugs, umbilical cord knotting, umbilical cord torsion and other factors. Chronic hypoxia is often related to systemic diseases such as hypertension and diabetes.

2. Fetal arrest occurs. The precursor to fetal arrest is that some people may experience abdominal pain or vaginal bleeding and other symptoms of threatened abortion, but some pregnant women do not have obvious symptoms. At 24 weeks, pregnant women can count fetal movements by themselves. If they feel that the fetal movements in the abdominal cavity decrease or stop, it means that there is a possibility of fetal growth retardation and they should go to the hospital for examination as soon as possible.

3. Fetal movement should be very obvious in the 6th month of pregnancy. If the baby does not move for a day, you should go to the hospital to rule out fetal arrest. However, the greater the gestational age, the lower the chance of fetal arrest. Six months is equivalent to 24 weeks, at which time the fetal movement is more obvious. The fetal movement appears at 18-20 weeks, and gradually increases, becoming most obvious around 8 months. In the late pregnancy, fetal movement may decrease slightly because the fetus has less space to move in the uterus, but it will not increase or decrease significantly. If the fetal movement increases or decreases significantly, it is an abnormal situation and you should go to the hospital immediately.
