The odor of vaginal discharge after pregnancy can affect the fetus if left untreated clinically. The odor of vaginal discharge is mostly caused by local inflammation of the vagina. If clinical intervention is not timely, retrograde infection may occur, and pathogenic bacteria may enter the uterine cavity and cause intrauterine infection, which may clinically arrest the development of the fetus. Therefore, for vaginal discharge with odor, it is recommended to go to the hospital in time to have the appropriate clinical examination, such as a routine high magnification white belt test, to understand the pathogenic bacteria infected, and then the clinical anti-inflammatory treatment should be given accordingly. In addition, in this case, if no cervical cancer screening has been done before pregnancy, it is recommended to do cervical cancer screening when clinically necessary to avoid the odor of the discharge caused by cervical cancer. During pregnancy, it is recommended that women must keep their vulva clean because after all, vaginal discharge is increased during pregnancy, and if vulva care is not enhanced, it is likely to lead to pathogenic bacterial infection and cause inflammatory reactions.
