There are 3 stages of leucorrhea in a month, corresponding to the follicular phase, ovulation phase and luteal phase of the menstrual cycle, which are caused by changes in hormone levels. In these 3 stages, the leucorrhea is mainly white and transparent, but the specific performance differs from stage to stage. 1. follicular phase: at this time, estrogen levels rise, leucorrhea secretion increases, milky white, relatively viscous, with a faint fishy smell or no odor; 2. ovulation phase: due to changes in the body’s hormone levels, cervical mucus dilution, at this time, leucorrhea increases, transparent texture, slightly sticky, egg white; 3. Luteal phase: the body progesterone level rises at this time, causing the amount of leucorrhea to become less, sticky and white paste. In the entire menstrual cycle, as long as the leucorrhea properties remain unchanged, it can be considered normal. If the leucorrhea is bloody, yellowish-green, fishy-smelling or pus-like, you need to consider the possibility of gynecological diseases, such as vaginitis. In this case, it is necessary to go to the gynecology department of the hospital for consultation to clarify the disease and provide symptomatic treatment. In daily life, you need to ensure the hygiene of your private parts by scrubbing with warm water in the morning and evening, and changing your underwear and pants regularly.
