Is brown secretion in early pregnancy a threatened abortion

If you are pregnant early, a small amount of brown secretions, and not accompanied by abdominal pain, obvious vaginal bleeding and other symptoms, generally not threatened abortion, may be due to changes in hormone levels in the early stage of pregnancy caused by a small amount of endometrial shedding, generally do not need special treatment. But if pregnant women appear in the early stage of pregnancy for many days, the amount of brown secretions, and gradually become bright red, accompanied by abdominal pain and other symptoms, can be considered as threatened abortion.
