If there is still brown bleeding from the vagina during the course of the treatment, this brown bleeding is the blood that used to be in the uterine cavity and was not discharged in time, and when it is discharged it is brown, maybe a little bit every day, and the amount is not much, and it does not manifest clinically as pain in the lower abdomen, you can continue to arrange the treatment. If bright red blood appears during the process of settling the pregnancy, it means that there is a new detachment between the gestational sac and the uterine wall, which only leads to fresh bleeding. This situation is clinically more serious than brown bleeding, and it is recommended that if the embryo is well developed through ultrasound examination, bed rest and medication should be used.
