White discharge in late pregnancy is normal. The shortening of the cervical canal and dilatation of the cervical opening in late pregnancy is due to the shortening of the cervical canal after the fetus has entered the pelvis, which is a physiological manifestation and does not require special treatment. During this period, try to pay attention to keep warm and do not eat cold food, chilled drinks or cold will easily lead to an increase in white discharge. It is also necessary to pay attention to hygiene and cleaning, especially in the second trimester when the discharge increases, which can cause bacteria to multiply and proliferate at the vaginal opening, and can lead to retrograde infection and vaginitis or infection in the uterine cavity; wear loose cotton underwear to facilitate ventilation and keep the area dry and clean.
