This statement is incorrect. Patients with a spontaneous abortion, also known as miscarriage, typically present with bleeding, cramping, and an open cervical os. An open cervical os allows the passage of products of conception, which is characteristic of a miscarriage that has already occurred or is in progress. Conversely, a threatened abortion may present with vaginal bleeding, but the cervical os remains closed, and the pregnancy may continue without incident.
