It is normal to have an increase in secretions before the onset of labor; if it is accompanied by symptoms such as odorous secretions and itching of the vulva, then it is a pathological condition such as vaginitis. 1. Normal phenomenon: In the period approaching labor, pregnant women may feel an increase in vaginal discharge because the cervical canal is gradually shortened with uterine contractions and the cervical opening is gradually dilated, and the cervical mucus will be discharged from the cervical canal, so pregnant women may feel an increase in vaginal discharge. 2. Pathological conditions: If the pregnant woman has more secretions and at the same time has vulvar itching or odor of secretions, it is considered to be due to bacterial and other infections that lead to vulvovaginitis, vaginitis and other pathological conditions. If a pregnant woman has more discharge in late pregnancy, accompanied by the above symptoms, it is recommended to consult a doctor in time, under the guidance of the doctor, improve the relevant examination, clarify the cause of the disease, and symptomatic treatment.
