What are the causes of vaginal bleeding in late pregnancy?

Everyone should know that the late pregnancy is a very important stage that women need to go through in their lives. In the early stages of pregnancy, that is, the first three months of pregnancy, pregnant women are more delicate because the embryo is still unstable at this time and miscarriage is very likely to occur. Therefore, pregnant women should pay more attention in the first three months of pregnancy and refrain from sexual intercourse and strenuous exercise. But some pregnant women still experience vaginal bleeding. What's going on?

However, vaginal bleeding in early pregnancy is not always caused by miscarriage. There are also the following common diseases:

1. Implantation bleeding:

The implantation of the fertilized egg occurs about 7 days after fertilization. At this time, most mothers do not have any particularly obvious reaction. A few women will have some red or pink blood, which is called implantation bleeding. There are generally no other accompanying symptoms such as abdominal pain or menstrual discomfort. This may just be a physiological reaction to the implantation of the fertilized egg. This situation does not require treatment, just keep it clean and it will not affect the development of the embryo.

2. Ectopic pregnancy (ectopic pregnancy):

A common acute abdomen in obstetrics and gynecology, with an incidence rate of 2%. Typical symptoms are postmenopausal abdominal pain and vaginal bleeding. Abdominal pain often manifests as dull pain or soreness on one side of the lower abdomen. When tubal pregnancy, miscarriage or rupture occurs, there is a sudden tearing pain in the lower abdomen on one side, often accompanied by nausea, vomiting, and a feeling of heaviness and distension in the anus.

3. Hydatidiform mole:

Hydatidiform mole is caused by the proliferation of trophoblastic cells of the placenta villi and interstitial edema after pregnancy, which forms blisters of varying sizes. The blisters are connected by pedicles into a cluster, and are named after their shape like grapes. They are also called vesicular fetal masses. Hydatidiform mole is divided into complete hydatidiform mole and partial hydatidiform mole. Generally, irregular vaginal bleeding begins around 8-12 weeks after menstruation. The amount of bleeding varies. If large blood vessels rupture, it can cause heavy bleeding and shock.

IV. Pregnancy with intrauterine contraceptive device:

Some women become pregnant while wearing an IUD (IUD pregnancy).

5. Bleeding related to genital inflammation:

Such as vaginitis, acute cervicitis, cervical polyps and endometritis. Among them, vaginitis and acute cervicitis are often accompanied by vulvar itching and abnormal leucorrhea (abnormal color and odor), and endometritis may be accompanied by lower abdominal pain.

6. Genital tumors:

Such as cervical cancer, endometrial cancer, etc.

So what should you do if you experience vaginal bleeding or bloody discharge in early pregnancy?

Because I have introduced to you many diseases and causes of possible bleeding, the most dangerous of which is ectopic pregnancy. If ectopic pregnancy is not diagnosed and treated in time, shock or even death of the pregnant woman may occur.

Through the above introduction, everyone should have understood that vaginal bleeding in pregnant women is not always caused by miscarriage. Some other diseases can also cause vaginal bleeding in pregnant women. Therefore, if pregnant women have vaginal bleeding, they should immediately go to a regular hospital for a detailed examination. After understanding the cause, targeted treatment should be carried out.
