Main Methods:

• Review of ultrasound imaging characteristics.
• Correlation of sonographic findings with pregnancy outcomes.

Main Results:

• Detailed description of ultrasound appearances for normal pregnancy, failed pregnancy, ectopic pregnancy, subchorionic hemorrhage, retained products of conception, and gestational trophoblastic disease.

Conclusions:

• Accurate interpretation of first-trimester ultrasound is crucial.
• Sonographic expertise guides timely and appropriate patient management.
