Threatened Miscarriage Symptoms & Diagnosis

Symptoms

The main symptom of threatened abortion is bleeding during the first 20 weeks of pregnancy, with or without abdominal cramping. The bleeding may be light or heavy.

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. Other tests may include:

• Ultrasound —a test that uses sound waves to examine the body
• Fetal heart monitoring—a procedure that places electrodes on the abdomen to detect the fetal heart rate (detectable at 8-10 weeks of pregnancy), and determine the strength and duration of uterine contractions
• Blood tests
