Cervical ulcer:
Cervical erosion, ulceration of the lining of the uterine cervix made evident by bright red or pink spots around its opening. The cervix is the part of the uterus (womb) whose tip projects into the upper region of the vagina. In the earliest stage of erosion, patches of mucous membrane are shed from the cervix.

Causes of cervical ulceration include:

Infection, Collagen Disease, Bacterial overgrowth, Malignant Tumors and External Stimuli. Cervical ulceration during pregnancy is rare.

Symptoms of cervical infection are:
Abnormal vaginal bleeding that occurs after intercourse, or between periods.
Unusual vaginal discharge that does not go away: discharge may be gray, white or yellow in color.
Painful sexual intercourse.
Pain in the vagina.
Pressure or heaviness in the pelvis.
Painful urination.
Diagnosis:
A pelvic exam
A specimen collection
It is important to note that cervical ulcer is not the only cause of these symptoms. If you start experiencing them, she should talk to a doctor to rule out more serious causes.
