Placenta Previa

What is placenta previa?

Placenta previa is a pregnancy condition where the placenta covers part or all of the cervix. Normally, the placenta attaches to the top or side of the uterus. The exact cause of placenta previa is unknown, but recognizing symptoms and understanding risk factors can help manage the condition. 

What are the risk factors for placenta previa? 

While placenta previa can’t be completely prevented, certain factors may increase your risk. You may be more likely to develop placenta previa if you:

  • Smoke during pregnancy
  • Are older than 35
  • Have scarring on the uterus (from surgery or previous pregnancies)
  • Have had a prior pregnancy
  • Use cocaine during pregnancy

Talk with your health care provider about your risk and steps you can take to support a healthy pregnancy.

What are the types of placenta previa?

There are three types of placenta previa: 

  • Complete placenta previa: The placenta fully covers the cervix. 
  • Partial placenta previa: The placenta partially covers the cervix. 
  • Marginal placenta previa: The placenta is close to the cervix opening but does not cover it.

If you are diagnosed with placenta previa, your doctor will discuss the best care plan to ensure a safe delivery.

What are the signs and symptoms of placenta previa? 

Placenta previa may not cause noticeable symptoms early in pregnancy. However, signs can include: 

  • Bleeding during the second or third trimester 

If you experience bleeding, contact your doctor right away or go to the hospital. 

How is placenta previa diagnosed? 

Placenta previa is usually found during a routine ultrasound. If needed, your doctor may recommend additional ultrasounds later in your pregnancy to monitor whether the placenta moves away from the cervix as your uterus grows. 

What are the treatment options for placenta previa?

Treatment for placenta previa focuses on keeping you and your baby safe. Your care plan depends on how far along you are in your pregnancy: 

  • If you are in the second or third trimester with bleeding: You may need hospital monitoring to manage bleeding and help you reach as close to full term as possible. 
  • If you are near your due date and placenta previa has not resolved: A cesarean delivery (C-section) is usually recommended to ensure a safe birth for you and your baby.
