How to Diagnose Placenta Previa
Placenta previa is a condition in which the placenta attaches low on the uterus and partially or completely covers the cervix. If the placenta does not move out of the way as the uterus expands, it can create a problem during the latter part of pregnancy. As the cervix begins to dilate, the placenta will detach from the uterus and possibly cause severe vaginal bleeding. Learn how to diagnose placenta previa.

Before week 20 of pregnancy, placenta previa is normally found through a routine abdominal ultrasound. There are usually no symptoms present that would alert a mother that she has a low-lying placenta. If it is found on an ultrasound but isn't posing a problem for the mother, the provider will monitor her more closely and may order additional ultrasounds.

After week 20 of pregnancy, a mother with placenta previa may experience vaginal bleeding. If bleeding occurs, the doctor will do an abdominal ultrasound to determine if the placenta is low-lying. If it is, the doctor will typically require bedrest. If bleeding cannot be controlled, immediate delivery may be required.
