The causes of bleeding are commonly pre-eclampsia, placental factors, cervical factors, coagulation factors, etc. If you find vaginal bleeding, you should go to the hospital for consultation. Causes of bleeding: 1. bleeding in the bed: exclude ectopic pregnancy and diagnose preterm labor. 2.Placental factors: mid and late pregnancy are also related to placental factors, such as placenta praevia and placenta abruptio. 3.Cervical lesions: If cervical examination was not done before pregnancy, vaginal bleeding caused by cervical cancer cannot be excluded. 4, abnormal coagulation function: some pregnant women, due to abnormal coagulation function, phospholipid antibody syndrome, systemic lupus erythematosus, etc., the use of anticoagulant drugs, heparin, aspirin enteric soluble tablets can lead to abnormal coagulation function and cause bleeding. Therefore, bleeding during pregnancy, it is important to go to the hospital for relevant examination, screening and symptomatic treatment to ensure the relative safety of pregnancy. If it is preterm miscarriage, the doctor will guide the treatment with fetal preservation drugs. If it is placental factor, such as placenta praevia bleeding will lead to hemorrhage and endanger the life of mother and fetus, so you must go to the hospital in time. In addition, placental abruption can not only cause the death of the fetus, but also lead to placental stroke in the mother’s uterus, resulting in DIC in the pregnant mother, and even the uterus cannot be preserved because of DIC, so bleeding during pregnancy should be seen in the hospital in time. The solution to stop bleeding: i. Vaginal bleeding in early pregnancy is related to implantation and the use of anticoagulant drugs. The bleeding during implantation is due to the misalignment between the gestational sac and the uterus, which leads to the breakage of blood vessels, or the formation of blood clots followed by the breakage of blood vessels.
