First, it should be suffering from vaginitis. It is suggested to go to the hospital for a professional gynecologist during non-menstrual period, and make a routine leucorrhea by the way (whether there is vaginitis or not, and know what type of vaginitis it is).

Second, normal leucorrhea is different in different periods of menstruation. Generally, during ovulation, there are more leucorrhea. At this time, the leucorrhea is transparent, and it is pulled for a long time, a bit like a runny nose. It is also a little 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.

Third, pay more attention in daily life: it is best to wear loose cotton underwear, and underwear should be changed frequently. Wash vulva with warm water (in a special basin) every day, preferably in the shower, and wash underwear in a special basin. You'd better expose your underwear to the sun and iron it with boiling water. Eat less sweets and drink more yogurt.

If underwear is washed together, or there is no special basin, it will be contagious, so you should also pay attention to personal hygiene at ordinary times.
