There are several possible causes of cervical bleeding, some of which are quite serious. The NIH recommends that patients with unexplained vaginal bleeding see a doctor, who can examine the cervix in order to determine the cause of the bleeding. The position and texture may have benign hormonal causes and are less worrying.
Unexplained cervical bleeding that is clearly distinct from normal menstrual bleeding or possible implantation bleeding is a symptom of several possibly serious conditions and is a cause for concern. The Mayo Clinic notes that bleeding is a possible symptom of cervicitis, an inflammation of the cervix that can be caused by disease, including sexually transmitted infections, or by allergies or bacterial overgrowth. WebMD notes that bleeding is also a possible symptom of cervical cancer.
Wikipedia notes possible causes of a soft or high cervix that are much less alarming. Hormonal changes that precede ovulation typically cause the cervix to become high and soft, and these changes are perfectly normal. The cervix also softens late in pregnancy in preparation for dilation and childbirth. This is also perfectly normal.
According to WebMD, one possible cause of cervical bleeding that may not be problematic is a Pap test, after which some bleeding is possible.
