If bleeding occurs in the early stages of pregnancy, it may indicate threatened miscarriage. However, bleeding may also occur during uterine contractions. To determine whether the bleeding is caused by uterine contractions, you need to go to the hospital for examination and have a doctor determine. Bleeding during pregnancy must be taken seriously as it concerns the lives of both people. This article introduces the causes of uterine contraction bleeding and early pregnancy bleeding. Let’s learn about it together. 1. Will uterine contractions cause bleeding? Yes, especially in the early stages, when fetal development is very unstable and uterine contractions may cause bleeding reactions, and in severe cases may even cause miscarriage. In the second trimester, normal uterine contractions will not be accompanied by vaginal bleeding. When uterine contractions cause bleeding, you should pay attention to whether it is placental abruption. Premature birth will cause regular uterine contractions and abdominal pain, which are considered to be symptoms of premature birth. 2. Causes of bleeding in early pregnancy The most common abnormality in early pregnancy is vaginal bleeding, which is heavy, contains blood clots, and is accompanied by bouts of abdominal pain. The main causes of bleeding in early pregnancy are as follows: First, miscarriage 1. There are many reasons for miscarriage, mainly: ① Genetic defects prevent the embryo from developing normally; excessive exposure to harmful chemicals (such as arsenic, benzene, formaldehyde, ethylene oxide, etc.) and physical factors (such as radiation, noise and high temperature, etc.) cause miscarriage. ② Miscarriage may also occur if the mother suffers from serious systemic diseases, reproductive organ malformations or tumors, endocrine disorders, etc. 2. The main symptoms of miscarriage are vaginal bleeding and abdominal pain in early pregnancy. According to the different stages of miscarriage development, miscarriage can be divided into threatened miscarriage, inevitable miscarriage, incomplete miscarriage and complete miscarriage. Generally, during the threatened abortion stage, vaginal bleeding is less and abdominal pain is mild. If there is no abnormality in the fetal development, the bleeding will stop after pregnancy preservation treatment and the pregnancy can continue. If the amount of bleeding is more than menstruation and is accompanied by severe abdominal pain, miscarriage is bound to occur and further treatment is required. Second, ectopic pregnancy Ectopic pregnancy is also called ectopic pregnancy. It means that the fertilized egg fails to enter the uterus normally and implants in other parts of the uterine cavity (fallopian tube, uterine cornu, abdominal cavity or ovary). In layman's terms, the fertilized egg "sleeps" outside the uterus. The walls of these areas are thin and narrow. When the fertilized egg grows bigger, it will pass through the wall tube, destroy the blood vessels and cause heavy bleeding. |
