Normal leucorrhea is different in different periods of menstruation. Generally, during ovulation, there are more leucorrhea. At this time, the leucorrhea is transparent, the drawing is longer, a bit like a runny nose, and there are more during menstruation. If you have lower abdominal pain and more leucorrhea, it may be a phenomenon of cervical erosion, adnexitis or pelvic inflammatory disease. If it is severe cervical erosion, it will also cause abdominal pain. You should go to the hospital for a check-up and make a definite diagnosis. If leucorrhea is fishy, thin and frothy, it is generally trichomonal vaginitis. If leucorrhea is as thick as bean curd residue, it is more likely to be fungal vaginitis. If leucorrhea stinks, it is easier to get bacterial vaginosis. Vaginitis should be judged by a doctor, and don't wash the vagina with lotion when it is unnecessary.
