Does bleeding in early pregnancy mean miscarriage? What is the cause of bleeding in early pregnancy?

The condition of the fetus in early pregnancy is not very stable, and it is easy to have unexpected situations due to some adverse stimulation, among which bleeding is the most common. When pregnant women experience vaginal bleeding in early pregnancy, they often worry and think that miscarriage has occurred. So is bleeding in early pregnancy a miscarriage?

1. Is bleeding in early pregnancy miscarriage? <br/>Vaginal bleeding in early pregnancy is generally considered to be caused by threatened miscarriage, and there will also be discomfort and pain in the lower abdomen. Because the placenta has not yet developed in early pregnancy, the embryo implantation is not stable, so miscarriage is prone to occur. It is recommended to go to the obstetrics and gynecology department for an abdominal B-ultrasound examination in time, and to help preserve the fetus by injecting progesterone or taking oral preserving drugs. However, if the fetus preservation fails, further curettage surgery is required.

Causes of bleeding in early pregnancy
1. Bleeding during implantation of fertilized egg <br/>In fact, the cause of bleeding in early pregnancy is not necessarily miscarriage, but may also be a small amount of vaginal bleeding caused by the implantation of fertilized egg. This usually lasts for two to three days and there will be no other discomfort symptoms, so no special treatment is required.
2. Subchorionic bleeding <br/>In the early stages of pregnancy, as the fertilized egg develops, the chorion will gradually form. If the chorion separates from the endometrium, it can also cause vaginal bleeding, but it will only cause slight discomfort such as tightness in the abdomen, which is usually not a big deal.

3. Biochemical pregnancy <br/>If a biochemical pregnancy occurs, women will have vaginal bleeding symptoms in the early stages of pregnancy. This is mainly due to the failure of the sperm and egg to implant in the uterus or implantation failure, which is related to the poor quality of the fertilized egg. The amount of vaginal bleeding at this time is similar to the amount of menstruation.
4. Ectopic pregnancy <br/>Ectopic pregnancy can cause vaginal bleeding around 7-8 weeks of pregnancy, accompanied by severe abdominal pain. In severe cases, it can even cause massive intra-abdominal bleeding and even shock. Once an ectopic pregnancy is detected, surgery must be performed in time to terminate the pregnancy.
