The increase in leucorrhea after taking the pill is mainly due to the fact that the short-acting pill is a combination of estrogen and progestin, which contains estrogen, then estrogen will lead to an increase in vaginal discharge and cervical discharge, so the leucorrhea will increase. However, if there is an increase in vaginal discharge with yellow color and odor, it is not caused by oral contraceptives, but by inflammation of the vagina, which is just a coincidence. It is recommended to go to the hospital for a routine examination of the leukorrhea and to know the pathogenic bacteria of the infection through laboratory tests, and then to give the appropriate medication for treatment. It is recommended that women must keep their vulva clean in their daily life and insist on bathing and washing their vulva once a day to avoid pathogenic bacteria infections. If oral contraceptive pills are taken, then it is better to do the corresponding examination before taking the pills and exclude contraindications before taking the pills orally.
