Bleeding in pregnancy is generally more likely to be successful in preserving the fetus if the amount of bleeding is not too large. If the amount of bleeding is more, or even if you see flesh-like tissues being discharged, it is generally very difficult to preserve the fetus successfully. Vaginal bleeding after pregnancy may be due to chromosomal abnormalities of the embryo, maternal luteal insufficiency, trauma and other factors, if the amount of bleeding is small, through bed rest, under the guidance of the doctor to use drugs to protect the fetus, there is still a high probability of successful preservation of the fetus. If the amount of bleeding is very large, and you can even see flesh-like tissues flowing out, there is basically no possibility of successful birth control at this time, and you need to remove the residual tissues in the uterine cavity in a timely manner to reduce the bleeding and prevent the symptoms of hemorrhagic shock. Bleeding during pregnancy requires prompt medical examination and treatment as prescribed by the doctor.
