Placenta previa is a condition during pregnancy where the placenta covers the opening of the uterus, either partially or completely. It's like having a blanket over the door. This can cause serious bleeding before, during, or after childbirth because the placenta is in the way of the baby's exit during delivery.

The exact cause isn't known, but certain factors increase the risk. Women who have had surgeries on their uterus, like a C-section or abortion, or those with a uniquely shaped uterus are more likely to have it. Other risk factors include smoking, cocaine use, being older, and undergoing in vitro fertilization.

The number one symptom to look out for is sudden vaginal bleeding without pain, especially after the 20th week of pregnancy. The bleeding can vary from light to heavy and may stop and restart without warning.

Placenta previa is usually found during an ultrasound in pregnancy. This test lets doctors see where the placenta is lying about the cervix.

The treatment plan might include bed rest and monitoring at home for mild cases. In more serious situations, a C-section delivery might be needed, especially if the bleeding doesn't stop or the baby's health is at risk. Doctors might also recommend medication to help with the baby's lung development if an early delivery is necessary.

If you experience heavy bleeding, it's crucial to seek emergency medical help immediately. It's better to be safe and get checked out right away.

It's important to follow your doctor's advice closely, including taking it easy and avoiding exercise or anything that could trigger bleeding. Stay alert to your body's signals and plan to get to the hospital quickly.

With careful monitoring and medical care, most women with placenta previa can have a healthy pregnancy and delivery. The key is early detection and following your healthcare provider's guidance to manage the risks.
