Pregnancy outcome after a primary antenatal hemorrhage between 16 and 24 weeks' gestation

Overall pregnancy outcome after a primary light episode of antenatal hemorrhage between 16 and 24 weeks' gestation is fairly good. The prognosis is worse for heavy bleeding previa and nonprevia bleeding cases, but based on 95% confidence intervals, a normal outcome would be expected in greater than 50% of the placenta previa pregnancies vs a less than 50% expectation in nonprevia bleeding pregnancies.
