Normal leukorrhea is milky white, with no odor or a faint fishy smell. In the case of abnormal leucorrhea, the color often changes as follows: 1. yellow leucorrhea may appear. 2. purulent leucorrhea may appear. 3. there may be blood in the leucorrhea or mixed with blood. In addition, some people may have a large amount of vaginal discharge like slop, which is an abnormal phenomenon. Therefore, once you find out that your leucorrhea is abnormal, you must go to the hospital for appropriate examination, such as gynecological examination to find out whether there are abnormalities in the vagina and cervix, and whether there is inflammation in the pelvis, and it is recommended to do routine laboratory tests for leucorrhea, screening for cervical cancer, and if necessary, ultrasound examination to find out whether there are lesions in the endometrium.
