Placenta previa

Placenta previa is where the placenta is completely or partially over the cervix.

This is a condition where the placenta is implanted completely or partially over the cervix, in the lower part of the uterus, thereby obstructing the birth canal.

Placenta Previa usually occurs in women who have had more than one pregnancy or have abnormalities of the uterus. A sign of Placenta Previa is painless vaginal bleeding after the seventh month with no apparent cause.

When bleeding is profuse, blood transfusions may be needed. However, when the bleeding is minor, bed rest and little activity are usually advised. A caesarean section will most likely be performed, but the decision to do so will only be taken close to your due date as a low-lying placenta in early pregnancy may shift to a normal position as the uterus grows.
