Why does bleeding occur during pregnancy?

A small number of pregnant women will experience vaginal bleeding when they just become pregnant. During this period, the embryo implantation is not particularly stable, the pregnant woman's physical condition declines, and there are problems with the immune system, etc., which can easily lead to some unpredictable risks and often cause bleeding. In addition, some diseases are also important causes of bleeding, such as cervical lesions, ectopic pregnancy, etc.

Why does bleeding occur during pregnancy?

1. Cervical lesions

If a pregnant woman has cervical lesions before pregnancy, resulting in erosion, or already has cervical polyps, then after pregnancy, it is very likely that the surface capillaries will rupture and bleed due to hormonal changes. Therefore, when a pregnant woman has symptoms of vaginal bleeding in the early stages of pregnancy, a cervical examination should be performed.

2. Ectopic pregnancy

Ectopic pregnancy can also cause bleeding in early pregnancy because the fertilized egg implants outside the uterus and cannot provide the embryo with sufficient nutrients, causing the gradually developing fertilized egg to expand the fallopian tube wall and cause the tube wall to rupture. Bleeding caused by ectopic pregnancy usually occurs during the 7th to 8th week of pregnancy, accompanied by severe abdominal pain or massive intra-abdominal bleeding.

3. Hydatidiform mole

Pregnant women with hydatidiform mole may also experience pregnancy bleeding, accompanied by severe morning sickness or palpitations. Women who are younger than 20 or older than 35, who have a history of miscarriage or hydatidiform mole, etc. should be careful about whether they may get pregnant with hydatidiform mole again.

Symptoms of bleeding in early pregnancy

1. Bleeding pattern

If the blood is brown, expectant mothers do not need to worry too much. Brown blood means that the bleeding has stopped. Just get more rest and avoid exercise. If the blood is bright red, seek medical attention immediately. Ectopic pregnancy usually causes a small amount of vaginal bleeding, and in severe cases, there may be intra-abdominal bleeding; the bleeding caused by hydatidiform mole can be more or less, but if it is not discovered early, it may cause heavy bleeding.

2. Pain

Most expectant mothers who suspect they have had early miscarriage will experience back pain and lower abdominal pain similar to menstruation. When the pain is severe, the pregnant woman will turn pale, have a faster heartbeat, and may also experience intra-abdominal bleeding. An ectopic pregnancy can cause abdominal pain, pale complexion, and rapid heartbeat; bleeding caused by a hydatidiform mole can cause severe lower abdominal pain.

It turns out that there are several reasons why bleeding occurs in early pregnancy. Pregnant mothers should take a good look at them. Pregnant mothers should pay more attention to rest in their daily lives, avoid overwork, and avoid too much psychological pressure. When having sex, they should be gentle and not too intense. Do not use drugs indiscriminately during pregnancy. Mothers with signs of miscarriage should not worry too much. If you can continue to be pregnant and give birth after bleeding, the chance of congenital abnormalities of the fetus will not increase.
