Causes of light bleeding during pregnancy

I believe that most pregnant friends will not be too unfamiliar with the symptom of having a small amount of bleeding after pregnancy. A small amount of bleeding after pregnancy is a common symptom. A small amount of bleeding after pregnancy will not only bring pain to pregnant women but also easily bring great psychological pressure to pregnant women. Therefore, we suggest that most pregnant friends should pay attention to this symptom. Below we introduce the reasons for a small amount of bleeding after pregnancy.

(1) Threatened abortion: When there is insufficient progesterone in the body to support the survival of the embryo, vaginal bleeding will occur. If the embryo implants in a bad position, such as too close to the cervix or cervix, too close to the fallopian tube or uterine cornu, it will also cause bleeding. Excessive fatigue or bad mood of the mother can also cause threatened abortion and vaginal bleeding.

(2) Ectopic pregnancy: This means that the embryo implants in an incorrect location, not in the uterine cavity, but more often in the fallopian tube, ovary, etc. Because the muscle layer of the fallopian tube wall is weak and insufficient to support the survival of the embryo, vaginal bleeding will occur.

(3) Fetal development stops: If either the sperm or the egg is unhealthy, the fertilized egg cannot develop normally and dies. In addition, exposure to toxic and harmful environments, exposure to drugs, and the mother's bad mood in the early stages of pregnancy can also cause the fetus to stop developing. An embryo that has arrested development may flake off and bleed.

(4) Cervical disease: Some pregnant women have cervical inflammation before pregnancy, or cervical erosion, or cervical polyps. Inflammation exposes the cervical blood vessels, which are prone to bleeding. In a very small number of cases, bleeding may be caused by precancerous cervical cancer or cervical cancer.

(5) Hydatidiform mole: This is an extremely rare condition in which there is no fetus in the intrauterine pregnancy, but only a vesicular fetus that looks like a grape bead. Vaginal bleeding will occur at a very early stage, and the blood chorionic gonadotropin level will be abnormally elevated. B-ultrasound may show snow-like changes in the uterus, but no fetus is seen. In this case, hydatidiform mole should be diagnosed.

(6) Placenta problem: The placenta gradually forms after 10 weeks of pregnancy. If the placenta is located close to the intrauterine os or covers the intrauterine os, it will cause vaginal bleeding. This is because there is a small separation between the cervical tissue and the placenta, causing bleeding from small blood vessels.
