When a woman has stretched leucorrhea before her upcoming period, it may be caused by ovulation just occurring in the ovaries, a situation where ovulation is delayed. It may also be related to a woman’s uterine cold or greater dampness in her body, resulting in more leucorrhea secretion and high degree of straining. If a woman is a leucorrhoea without vulva itching, odor, you can use warm water for cleaning, keep the vulva clean and hygienic, eat more hot food, pay attention to proper rest, can be temporarily observed. If you have vulvar itching and other abnormalities, most of them are combined with vaginitis and need to be treated with lotion or medication in time. During a menstrual cycle, the amount of leukorrhea secretion is affected by the estrogen secreted by the ovaries in the body, which may increase or decrease.
