Women have leucorrhea that is snotty, sticky and clear. If the amount of leucorrhea is not too much and there is no discomfort, it is normal leucorrhea, which mostly occurs in two special periods. First, women can have this kind of leucorrhea during ovulation. During ovulation, the level of hormones such as pregnancy, estrogen and luteinizing hormone increases, and the patient’s vaginal secretion glands secrete vigorously which can change the leucorrhea’s nature and make it more viscous and drawn. When the patient appears this kind of leucorrhea, it mostly suggests that the patient has ovulation. Secondly, this kind of leucorrhea can also appear after the patient takes the emergency contraceptive pill. The main component of the emergency contraceptive pill is progestin, which can also change the nature of the leucorrhea, making it more viscous and sticky, so that the cervical opening of the patient is blocked and not conducive to sperm penetration, so it can achieve the effect of contraception.
