Pregnant women can use gynecological suppositories, such as bitter ginseng gel and mycobacterial suppositories, subject to the drug instructions. After pregnancy, due to the change of hormonal secretion in the body, the glycogen of the vagina decreases and the vaginal environment changes, the immunity of pregnant women decreases and bacterial infections are prone to occur. If you have increased vaginal discharge or odor during pregnancy, you should consider the possibility of vaginitis. You need to go to the hospital for a routine leuko-band examination to clarify the type of bacteria that cause vaginitis and then use the medication. During pregnancy, you should pay attention to keep your perineum clean, wash and change it regularly, wear breathable cotton underwear, eat more food rich in high quality protein and vitamins to strengthen your resistance, and use local medication gently during early and late pregnancy to avoid stimulating the uterus and inducing contractions.
