What should I do if I have vaginal bleeding at 31 weeks of pregnancy?

During pregnancy, a woman's body will undergo some changes as the fetus grows, and the body's hormones are also prone to some changes. Vaginal bleeding in pregnant women at 31 weeks of pregnancy is relatively dangerous for the fetus. It may be a precursor to miscarriage and requires detailed examination and treatment. Avoid strenuous exercise and long-term walking. You can eat more fetal-protecting foods and pay attention to the amount of vaginal bleeding.

What should I do if I have vaginal bleeding at 31 weeks of pregnancy?

This situation is most likely a premature birth, and you need to go to the hospital for diagnosis and examination to prevent the fetus from being in danger. Generally speaking, vaginal bleeding during pregnancy is an abnormal condition, and you should consider the possibility of threatened abortion. It is best to go to the hospital for relevant gynecological examinations.

Symptoms of threatened miscarriage

The gestation period of a pregnant woman lasts about 40 weeks. During this long period of time, expectant mothers must do a good job of health care during pregnancy. In addition to some necessary physical examinations, food, clothing, housing and transportation must be properly arranged, especially to prevent the occurrence of threatened abortion during pregnancy.

1. Vaginal bleeding. Bleeding is often considered the first sign of miscarriage, but it is normal to have vaginal bleeding in the first three months of pregnancy. If vaginal bleeding is accompanied by pain, you need to pay special attention because it may be a sign of miscarriage.

2. During the gynecological examination, the cervix was not dilated, the amniotic sac was not ruptured, the size of the uterus was consistent with the month of amenorrhea, the urine pregnancy test was positive, and the ultrasound examination showed fetal heart rate and fetal movement waves. If the embryo is normal and the cause of the miscarriage is eliminated, the bleeding will stop, there will be no uterine contractions, and the pregnancy can continue.

3. Severe vomiting and inability to eat will lead to dehydration and electrolyte imbalance, which may endanger the lives of the fetus and pregnant women in severe cases.

Causes of threatened miscarriage

1. The mother suffers from a systemic disease. Such as acute severe infectious diseases, chronic diseases (such as severe anemia, severe hypertension, heart disease, chronic nephritis, etc.), vitamin deficiency, and chronic poisoning such as mercury, lead, and alcohol can all cause miscarriage.

2. Incompatible blood types. Due to the production of antibodies in the mother's body due to previous pregnancy or blood transfusion of RH factors or incompatible ABO blood type factors, when these antibodies enter the fetus through the placenta and agglutinate with red blood cells during this pregnancy, they cause hemolysis and lead to miscarriage.

3. Endocrine disorders. Excessive estrogen and insufficient progesterone are the causes of early miscarriage. Because at 12 to 14 weeks of pregnancy, the placenta is forming and replacing the corpus luteum.

4. Chromosome abnormality. Chromosome studies of spontaneously aborted fetuses revealed that 60% had karyotype abnormalities. Abnormal karyotype is often accompanied by a structural abnormality such as that of the fetus or placenta.

5. Abnormal emotions. Excessive tension, fear, and severe mental stimulation can all cause miscarriage.
