Understanding Placenta Previa -- Symptoms

What Are the Symptoms of Placenta Previa?

The main symptom of placenta previa -- and the greatest risk to you and your baby -- is vaginal bleeding. If you have bled too much, you may have other symptoms, such as anemia, pale skin, rapid and weak pulse, shortness of breath, or low blood pressure. The bleeding that signals placenta previa may occur at the end of the second trimester or beginning of the third trimester. It may be heavy or light.

Bleeding is usually painless, and it may happen without labor or during labor. Mothers with placenta previa are also at increased risk of delivering prematurely, before 37 weeks of pregnancy.
