Bleeding in the early stages of pregnancy may be caused by miscarriage or ectopic pregnancy. Miscarriage can be partially preserved and ectopic pregnancy must be terminated. 1. Miscarriage: including premonitory miscarriage, inevitable miscarriage, incomplete miscarriage, complete miscarriage, and retained miscarriage. (1) Pre-eclampsia: after bed rest and nutritional support, when bleeding stops and the embryo is still alive, the pregnancy can continue. If the clinical symptoms worsen, the embryo is not well developed and miscarriage is inevitable, the pregnancy should be terminated. (2) Inevitable miscarriage, incomplete miscarriage, and retained miscarriage: after diagnosis, it is necessary to remove the embryo and placental tissue, and the pregnancy cannot be continued. (3) Complete miscarriage: the fetus and placenta have been expelled, and the pregnancy has been terminated without the need for fetal preservation. (2) Ectopic pregnancy: the end is often miscarriage and pregnancy rupture. The pregnancy cannot be completed and should be terminated promptly after diagnosis. Bleeding with blood clots in the first trimester should go to the hospital in time and follow the doctor’s instructions. If necessary, terminate the pregnancy.
