If it is in the middle of the menstrual cycle, there is no special discomfort, and the brown discharge clears completely after 2-3 days belongs to ovulatory bleeding and does not require treatment. If the IUD is placed, an ultrasound should be performed to determine if the IUD has shifted down or shifted, if it has shifted down, it should be removed in time.
