What Is Placenta Previa?
Placenta previa is a condition during pregnancy where the placenta lies low in the uterus. In some cases, it covers part or all of the cervix. The placenta is an organ that gives your baby food and oxygen. Normally, it attaches higher up in the uterus. However, with placenta previa, it blocks the birth canal. Because of this, it can affect your delivery plan. Placenta previa can lead to bleeding and other risks during pregnancy. It is important to know the symptoms and options for delivery if you have this condition.
Symptoms and Warning Signs
Placenta previa often causes painless bleeding during the second or third trimester. However, some women may not have any symptoms. It is important to watch for warning signs, especially if you are at risk. For example, you should look out for:

Impact on Your Delivery Plan
Placenta previa can change how you deliver your baby. Because the placenta blocks the cervix, a vaginal birth is usually not safe. Instead, most women with placenta previa need a planned C-section. However, your doctor will decide the best time for delivery based on your health and your baby’s growth. If you have heavy bleeding, you may need to deliver earlier. In some cases, you may need to stay in the hospital for close monitoring.
Treatment and Management Options
Treatment for placenta previa depends on your symptoms and how far along you are. For example, your doctor may suggest:
In addition, your doctor may give you medicines to help your baby’s lungs mature if early delivery is needed. The goal is to keep you and your baby safe until delivery.
