Luteal bleeding usually heals after about 3-5 days, but the duration of luteal bleeding may vary because each person has a different constitution, the severity of the condition, the degree of luteal hyperplasia in the body and the progesterone value. The most common type of luteal bleeding is non-pregnancy bleeding and pregnancy bleeding. Non-pregnancy bleeding is usually caused by the rupture of the corpus luteum, and the amount of bleeding is usually small, but there are serious cases of hemorrhage, resulting in hemorrhagic shock and other adverse consequences, so it is usually necessary to actively receive conservative treatment and surgical treatment. In case of luteal bleeding during pregnancy, it is usually caused by low progesterone, which must be treated with oral or intramuscular progesterone in time.
