What Is Placenta Previa?
Placenta previa is a condition during pregnancy where the placenta covers part or all of the cervix. The placenta is an organ that gives your baby food and oxygen. Usually, it sits high in the uterus. However, in placenta previa, it is lower and blocks the birth canal. Because of this, placenta previa can change your delivery plan. For example, many women with this condition need a cesarean section (C-section) instead of a vaginal birth. Early diagnosis and careful planning are important for a safe delivery. Knowing about placenta previa symptoms, diagnosis, and delivery options helps you prepare.
Symptoms and Warning Signs
Placenta previa often causes painless, bright red vaginal bleeding in the second or third trimester. However, some women may not have any symptoms. Still, it is important to watch for warning signs. If you notice any of these, contact your doctor right away:

How Placenta Previa Is Diagnosed
Doctors usually diagnose placenta previa with an ultrasound. This test uses sound waves to make pictures of your baby and placenta. Sometimes, a transvaginal ultrasound gives a clearer view. If you have placenta previa symptoms, your doctor may also check your health and your baby’s well-being. In rare cases, an MRI may be used for more detail. Early diagnosis helps plan the safest delivery.

Your doctor will plan the timing based on your health and your baby’s growth. Sometimes, you may need to stay in the hospital for close monitoring. If you have heavy bleeding, your doctor may deliver your baby early. Planning ahead helps keep you and your baby safe.

When to See a Doctor
