Vaginal discharge increases during pregnancy due to the level of progesterone, but there should be no obvious signs of discomfort and the colour and smell of the discharge should not be abnormal.
Most women do not develop vaginitis during pregnancy. However, the hormonal changes during pregnancy lead to an increase in sugar in the vaginal epithelium, providing a good environment for the growth of bacteria and Candida. The body’s immune system is also reduced during pregnancy, so vaginitis is more common during pregnancy than during non-pregnancy, especially in patients with combined diabetes or autoimmune diseases. The majority of vaginitis during pregnancy is mycosis fungoides, also known as vulvovaginal pseudomonal vaginosis.
