[15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]

Both abdominal and vaginal ultrasound may be used, but vaginal ultrasound allows for earlier visualization of the pregnancy. With obstetric ultrasonography the gestational sac (intrauterine fluid collection) can be visualized at 4.5 to 5 weeks gestation , the yolk sac at 5 to 6 weeks gestation, and fetal pole at 5.5 to 6 weeks gestation.
An abdominal pregnancy is a rare type of ectopic pregnancy where the embryo or fetus is growing and developing outside the uterus, in the abdomen, and not in a fallopian tube (usual location), an ovary, or the broad ligament. [ 1][ 2][ 3] Because tubal, ovarian and broad ligament pregnancies are as difficult to diagnose and treat as abdominal ...
