If you have bad odor like yellow water, this situation is considered to be a sign of inflammation and infection, because under normal circumstances, the bad odor will not have a bad smell or a slightly fishy smell. If there is a foul odor, consider that it is caused by pelvic inflammatory disease, it is best to do an ultrasound examination to determine this situation. You also need to pay attention to hygiene and washing. You should also pay attention to the diet, do not eat spicy and stimulating food, otherwise it will easily lead to aggravate the symptoms of inflammatory infection, which will easily lead to increased discharge.
