Bleeding during pregnancy until delivery

During pregnancy, if there is continuous bleeding, you should pay attention to it. The most common cause of this situation is placenta previa. If there is early placental detachment, it will often cause continuous bleeding in pregnant women. At this time, you must go to the hospital for treatment and provide enhanced care at ordinary times. In order to avoid adverse effects on pregnancy care due to this situation, let’s take a look at this aspect.

Bleeding during pregnancy until delivery

Vaginal bleeding in pregnant women should not be ignored. Vaginal bleeding during pregnancy is a sign that the pregnancy is in a dangerous state. The amount of bleeding may be as much as hundreds of milliliters or as little as a few milliliters. Generally, the greater the amount of bleeding, the more critical the situation, but not all bleeding is visible, so clinically the patient's condition is not assessed solely based on the amount of bleeding that can be seen. In addition, the amount of bleeding of different diseases is sometimes not proportional to their actual severity.

The causes and clinical significance of bleeding in the three different stages of pregnancy, early, mid and late, are generally different, and the treatment methods are also different.

1. Early pregnancy (before 12 weeks of pregnancy)

Common bleeding is caused by miscarriage and ectopic pregnancy.

2. Second trimester (13-27 weeks of pregnancy)

Common causes include bleeding due to cervical insufficiency and hydatidiform mole.

3. Late pregnancy (28 weeks of pregnancy to delivery)

Common causes include placenta previa and placental abruption.

When the fertilized egg implants in the endometrium, it affects the tiny blood vessels in the endometrium and causes punctate implantation bleeding. This usually occurs during the menstrual cycle and is mostly normal.

Light vaginal bleeding or brown discharge during the first three months of pregnancy, sometimes accompanied by abdominal or back pain, is often a sign of miscarriage.

Late miscarriage after 12 weeks of pregnancy is rarely associated with chromosomal abnormalities. A molar pregnancy is a condition in which the fetus does not develop normally. Most miscarriages in the middle or late stages are caused by a normal fetus that cannot continue to develop due to various reasons. For example, severe uterine fibroids can make the uterus unable to maintain pregnancy.

Brown blood in early pregnancy is a sign of fetal leakage

In the early stages of pregnancy, many pregnant women have experienced vaginal bleeding, but most of them are small amounts of brown blood or just brown leucorrhea. The older generation will say that this is because of miscarriage. Don't panic. Brown blood may be caused by previous ovulation bleeding, implantation bleeding, or uterine blood accumulation. Go to the hospital in time to find out the cause.

The early stages of pregnancy are a relatively dangerous period, as pregnant women not only have to endure morning sickness, but also have to worry about the baby's death all the time. Bleeding is an alarm during pregnancy. Many pregnant women will be particularly worried when they find themselves bleeding. So what is the cause of bleeding in early pregnancy?

1. Miscarriage

Abortion refers to the phenomenon that the pregnancy ends before 28 weeks of pregnancy when the fetus cannot survive after leaving the mother's body. Miscarriage is most likely to occur in the early stages of pregnancy, which may be related to chromosomal abnormalities of the fertilized egg, poor embryo development, etc.

Symptoms: In the first 3 months of pregnancy, there is slight vaginal bleeding or brown discharge, with or without the discharge of blood clots and products of conception, sometimes accompanied by abdominal or back pain, which is often a sign of miscarriage.

2. Ectopic pregnancy

An ectopic pregnancy is a pregnancy outside the uterus, and a normal pregnancy is one in which the fertilized egg implants in the endometrium. It is also possible that the fertilized egg implants in the fallopian tube, ovary, abdominal cavity or other parts outside the uterine cavity. This kind of ectopic pregnancy is commonly known as ectopic pregnancy.

Symptoms: Bleeding caused by ectopic pregnancy usually occurs around 2 months of pregnancy, accompanied by varying degrees of nausea and abdominal pain. Once tubal pregnancy ruptures, massive intra-abdominal bleeding and severe abdominal pain will occur, which may lead to shock.

3. Hydatidiform mole

Hydatidiform mole refers to a disease in which the villi that form the placenta grow and multiply abnormally, and the uterus is filled with grape-like blister-like particles.

Symptoms: If the hydatidiform mole is not discovered in the early stages, symptoms such as vaginal bleeding, anemia, and uterine enlargement will usually begin in the middle of pregnancy. More serious symptoms may cause hyperemesis gravidarum, pregnancy-induced hypertension syndrome (proteinuria, hypertension, edema), etc. Most patients with hydatidiform mole have intermittent small amounts of bleeding, but there may be repeated heavy bleeding in the meantime, and sometimes blisters may be found in the blood.
