During pregnancy, the placenta attaches itself to the uterus to provide the developing fetus blood, oxygen, and nourishment as well as removing waste from your baby. The placenta may implant itself at a low position in the uterus, during the early stages of pregnancy. Normally, as the uterus begins to expand to provide more room for your baby, the placenta moves upward but away of the cervix. If it doesn't move away, it may be blocking the opening of the cervix. This is known as placenta previa. If this does occur, the placenta will detach itself from the uterus in advance as the cervix begins to open up for labor. Generally, placenta previa can be detected before any severe harm is caused.
An abruptio placentae is a premature separation of the placenta from the uterine wall.

Previa in medical terms is often used as shorthand for placenta previa. Placenta previa is a condition in which the placenta is situated low in the uterus. Because of this malposition, at delivery the woman can experience a great loss of blood.
