Placenta previa is a complication in which the placenta is inserted partially or wholly in the lower uterine segment.
Explanation:
If the placenta does over lie the lower segment, as is the case with placenta previa, it may shear off a small section and may bleed.
This commonly occurs around 32 weeks of gestation, but can be as early as late mid trimester.
Placenta previa can be confirmed with an ultrasound . Women with placenta previa often present with painless, bright red vaginal bleeding.
