Placenta previa is a condition in which your placenta grows near or over your cervix (opening of your uterus). The placenta forms during pregnancy and provides oxygen and nutrition to your unborn baby. The placenta also removes waste products from the fetus.
There are different forms of placenta previa: 1  Marginal: The placenta is next to the cervix but does not cover the opening. 2  Partial: The placenta covers part of the cervical opening.  Complete: The placenta covers all of the cervical opening.
