The cervix is the lowest part of the uterus. It extends slightly into the vagina. This is where menstrual blood exits the uterus. During labor, the cervix dilates to allow a baby to pass through the birth canal (endocervical canal).Like any tissue in the body, the cervix can become inflamed for a variety of reasons. Inflammation of the cervix is known as cervicitis.Some women with cervicitis experience no symptoms. When symptoms are present, they can include:abnormal vaginal bleedingpersistent gray or white vaginal discharge that may have an odorvaginal painpain during intercoursea feeling of pelvic pressurebackachesThe cervix can become very inflamed if cervicitis progresses. In some cases, it can develop an open sore. Pus-like vaginal discharge is a symptom of severe cervicitis.Womb
