What causes bleeding during pregnancy?

The pregnancy process is very long and is divided into three stages: early pregnancy, mid-pregnancy and late pregnancy. The most dangerous period is the early pregnancy, but pregnant women in the mid-pregnancy and late pregnancy also need to pay more attention. Vaginal bleeding may occur at any stage. This phenomenon directly indicates that there is something wrong with the pregnant woman's body and needs to be adjusted in time. So what is the matter with bleeding in the middle of pregnancy?

First, what is the cause of bleeding in the second trimester of pregnancy? Cervical disease causes vaginal bleeding. Most women will have varying degrees of cervical disease after marriage. After pregnancy, as the pregnancy progresses, the level of progesterone in the pregnant woman's body continues to increase, causing the columnar epithelium of the cervix to move outward and the tissue to proliferate. The symptoms of cervical disease are significantly aggravated, and vaginal bleeding is prone to occur at this time; excessive sexual life, overeating of hot and irritating foods such as chocolate, peppers, longan, or hot pot can also aggravate bleeding symptoms. This type of bleeding is different from the bleeding caused by uterine contraction during spontaneous abortion, which causes the placenta to separate from the uterus. This type of bleeding does not directly affect the development of the fetus. As long as the bleeding is stopped in time, the pregnancy can still progress normally. However, if it is not treated in time, it will affect pregnancy and may eventually lead to miscarriage.

Second, threatened abortion causes vaginal bleeding. Threatened abortion can occur in the early or middle stages of pregnancy. Vaginal bleeding is a common danger sign during pregnancy, so it should be taken seriously. The amount of vaginal bleeding varies depending on the type of abortion. Most pregnant women experience paroxysmal pain in the lower abdomen. As the disease progresses, vaginal bleeding may gradually increase, and symptoms such as increased frequency and severity of abdominal pain, coldness in the abdomen, and sometimes inability to feel fetal movement may occur. If the amount of bleeding is heavy or the pain in the lower abdomen is frequent and severe, you should go to the hospital immediately regardless of day or night.

What is the cause of bleeding in the second trimester of pregnancy? Hydatidiform mole causes vaginal bleeding. Vaginal bleeding in pregnant women with hydatidiform mole usually begins 6-8 weeks after menopause and is often intermittent and recurring. The blood is dark red or brown, or there may be a small amount of coffee-colored secretions. The amount of bleeding varies, generally starting from a small amount and gradually increasing, and there are blister-like substances in the blood. Before heavy vaginal bleeding, there is often persistent abdominal pain due to increased and larger intrauterine bleeding and vesicular material, which causes the uterus to expand rapidly.
