Vaginitis is a very common gynecological issue among women, occurring countless times in every woman's life. Thus, the ability to get pregnant while having vaginitis indicates that there are no major issues with your body. Vaginitis itself does not affect the development of the fetus, however, during childbirth, it may lead to infections in the fetus. For instance, fungal vaginitis may cause oral thrush in children, and bacterial vaginitis may lead to infections of the uterine lining. In other words, vaginitis could potentially trigger infections during childbirth, affecting both the mother and the fetus. Throughout the pregnancy, it does not cause developmental deformities in the fetus.
