Severe pain, heavy bleeding, passage of clots or tissue, and hypotension are possible. Symptoms that are not accompanied by passage of tissue or cervical dilation constitute a threatened abortion. Uterine cramping with progressive cervical dilation indicates an inevitable abortion. Partial passage of products of conception (POC) with intrauterine retention of some tissue is an incomplete abortion. Fever, leukocytosis, pelvic tenderness, and malodorous cervical discharge suggest a septic abortion. Completed abortion is characterized by the passage of confirmed POC, followed by resolution of bleeding and closure of the cervical os.
