The placenta previa is a condition in which the placenta totally or completely covers the cervix. This is associated with severe bleeding throughout the tenure of pregnancy and during delivery.

Amniocentesis is the process of obtaining the amniotic fluid from the placenta of the mother and conduct genetic testing but this cannot be done in the woman who is bleeding vaginally. Internal fetal monitoring cannot be performed in the presence of vaginal bleeding. The contraction stress test is not performed in the gestational age.
