Bloody diarrhea is the vaginal discharge of a large amount of blood, sometimes accompanied by small blood clots. This kind of bloody discharge contains a small amount of fetal membranes and necrotic meconium. It is recommended to change sanitary napkins and keep the vulva clean by scrubbing the vulva with povidone-iodine twice a day when there is bloody discharge. It is also recommended that you change your underwear regularly, mainly to avoid bacterial invasion and infection. In addition, most of the bloody discharge will be cleared in about nine days, and then it will turn into plasma discharge, and then white discharge will appear. This kind of discharge often lasts for 4-6 weeks, during which time it is important to do a good job of cleanliness and hygiene to avoid causing infections.
