title: Second-trimester tubal pregnancy: a case report.
abstract: BACKGROUND
  Second-trimester tubal pregnancy is an infrequent diagnosis, as these pregnancies often present with symptoms during the first trimester.
  
  
  METHODS
  A previously asymptomatic woman presented with pelvic pain and vaginal bleeding at 4 months' gestation and was found to have a live, 14-week, tubal pregnancy.
  
  
  CONCLUSIONS
  Second-trimester symptoms, including nausea, vomiting, pelvic or abdominal pain, and vaginal bleeding, necessitate ultrasound to determine the pregnancy location, maintaining suspicion for a tubal or abdominal pregnancy.
