If a pregnant woman’s underwear keeps appearing wetter in the sixth month of pregnancy, two conditions should be considered. First, consider the possibility of increased vaginal discharge and vaginitis infection. After pregnancy, due to the influence of hormone level, the blood vessels in the perineum will become richer and the tissues in the perineum will be more fertile, which will lead to a wetter perineum and increase the probability of vaginitis. If there is more leukorrhea, it will lead to wet underwear and may cause odor in the vulva, so you need to go to the hospital for gynecological examination and routine leukorrhea. Second, it is also necessary to consider whether there is premature rupture of fetal membranes. There are pregnant women who have premature rupture of membranes in the very early stages of pregnancy, which can increase the risk of infection and premature delivery, and need to go to the hospital for examination.
