1. Abortion: The most common cause of early pregnancy bleeding is abortion. If the amount of bleeding is large or accompanied by severe abdominal pain, low back pain and other symptoms, it is likely to lead to abortion.
2. Premature delivery: Bleeding in early pregnancy may also lead to premature delivery, that is, the fetus is born less than 37 weeks during pregnancy. Premature babies may face many health problems, such as dyspnea, low weight, infection and so on.
3. Congenital malformation: In some cases, early pregnancy bleeding may increase the risk of fetal congenital malformation. For example, if the bleeding is caused by chromosomal abnormality, then the fetus may suffer from chromosomal abnormality syndrome.
4. Growth retardation: Bleeding in the first trimester may also lead to fetal growth retardation, that is, the fetus cannot reach the expected weight and height. This may affect the health and development of the fetus.
In short, early pregnancy bleeding needs to be paid enough attention, and timely medical treatment is very important.
