Early pregnancy is the most critical period of pregnancy. At this time, you must pay attention. If expectant mothers find that they have missed their period, they must take a pregnancy test first. If they are pregnant, they will then use ultrasound to confirm whether the fertilized egg is in the correct implantation position. After confirming that the pregnancy is normal, it is best to go to the hospital for regular check-ups to avoid accidents.
Under normal circumstances, if an expectant mother has vaginal bleeding and abdominal pain, this is medically called a threatened abortion and requires even more attention.
Threatened abortion refers to a small amount of vaginal bleeding and/or lower abdominal pain before 28 weeks of pregnancy, the cervix is not dilated, the fetal membranes are not ruptured, the pregnancy products have not been discharged, and the size of the uterus is consistent with the number of weeks of menopause. The clinical manifestations of early threatened abortion are usually early pregnancy reaction after menopause, followed by a small amount of vaginal bleeding or intermittent bleeding, or continuous dripping, red color, lasting for several days or weeks, no abdominal pain or slight lower abdominal distension and pain, low back pain and lower abdominal pain. Feeling of swelling. A miscarriage that occurs before the 12th week of pregnancy is called an early miscarriage; a miscarriage that occurs at the later 12th week is called a late miscarriage.
Miscarriage in early pregnancy is characterized by abdominal pain first and then vaginal bleeding. When miscarriage begins, the villi separate from the decidua and the blood sinuses open, which causes bleeding to begin. If the embryo is completely separated and expelled, the uterus will contract and the bleeding will stop. In late-term miscarriage, the placenta has already formed, so the symptoms are similar to those of premature labor. The placenta is expelled after the fetus is delivered, and there is usually not much bleeding.
The main causes of threatened abortion include the following aspects.
Embryonic aspects: The main reason is that the father\’s or mother\’s germ cells are not perfect. Although the germ cells that are not very sound are reluctantly combined to form an embryo, they will eventually die early and will not be able to reach full term delivery. Abortion caused by this reason is not too bad, it is the result of survival of the fittest. Other reasons, such as insufficient oxygen supply to the umbilical cord, amniotic fluid disease, placental viral infection, and certain gynecological inflammations, can also cause miscarriage. Malnutrition in pregnant women is also one of the causes of miscarriage. Some pregnant women suffer from severe nausea and vomiting in the early stages of pregnancy, resulting in extreme nutritional deficiencies, which have a great impact on the development of the embryo and are prone to miscarriage.
Maternal aspect:After a woman becomes pregnant, mental stimulation such as emotional instability, anger, and sadness will disrupt the activity of the cerebral cortex, causing contraction of the uterus and forcing out the embryo, or causing the embryo to die in the uterus. Acute infectious diseases such as influenza and rubella can cause miscarriage due to high fever and toxins released by bacteria and viruses. Endocrine disorders, such as dysfunction of the corpus luteum, pituitary gland, and thyroid gland, as well as excessive retroflexion of the uterus in uterine dysplasia, causing the uterine cavity to hinder the development of the embryo, may cause miscarriage.
Other aspects: Sexual life during the entire pregnancy should be cautious and inappropriate sexual life Especially in early pregnancy, it is easy to cause miscarriage. In the second trimester, sexual life should also be moderate, and sexual positions that press the pregnant woman\’s abdomen and rough sexual intercourse should be avoided to avoid causing miscarriage. Rough gynecological examination during the perinatal period can easily lead to miscarriage. This is especially important for pregnant women with weak constitutions. Drugs and certain chemical substances, such as quinine, carbon monoxide, aluminum, phosphorus, mercury, and benzene poisoning, often make it difficult to preserve the embryo. Physical factors such as radioactive substances, high temperatures, microwaves, noise, etc., chemical factors such as various metal substances such as mercury and lead, and chemical substances such as benzene, gasoline and organic pesticides are all high-risk factors that lead to threatened abortion.
