It is normal for the vaginal discharge to increase after pregnancy due to the rise of estrogen, but the increased discharge is milky white and sometimes egg white, which is normal. If the leucorrhea increases, is yellowish-purulent and smells bad, or if there is itching of the vulva, this is not normal and may be due to vaginitis. In the early stages of pregnancy it can cause preterm miscarriage or stop the development of the embryo. In the late stages of pregnancy, if the vaginitis is serious, it cannot be delivered vaginally, and if it is delivered vaginally, it sometimes causes severe laceration. Therefore, during pregnancy, if you have vaginitis, it is important to have it treated promptly.
