In the third month of pregnancy, pregnant women who have tofu crumb-like leucorrhea are considered to be infected with mycotic vaginitis. Tofu crumb-like leucorrhea is a typical manifestation of mycobacteria. During pregnancy, the change of vaginal environment and the decrease of resistance increase the probability of vaginitis, and mycobacteria are one of the most frequent vaginitis during pregnancy. The infection of mycobacteria can easily increase the risk of premature miscarriage and also cause damage to the vaginal mucosa of pregnant women. The first step is to do the routine of leucorrhea, and you can use medication under the guidance of your doctor, most of which will not affect the growth and development of your baby.
