Severe bleeding during pregnancy can be placenta previa

contemplative pregnant woman During my mom’s pregnancy with me, she was diagnosed with placenta previa, a condition in which the placenta lies very low in the uterus and covers all or part of the cervix. The cervix is the opening to the uterus that sits on the top of the vagina. If you have placenta previa, when your labor starts, your cervix begins to thin out and dilate (open up), and the blood vessels connecting the placenta to your uterus may tear. This can cause severe bleeding.

My mom remembers the day I was born, like it was yesterday. She remembers my Aunt running down the hall to get towels for her while she stood in the bathroom bleeding during her third trimester. She was rushed to the hospital and had an emergency Cesarean section (C-section) performed. My mom says she can still remember what the pressure felt like on her lower abdomen during the procedure.

We don’t know what causes placenta previa, which happens in about 1 in 200 pregnancies. If you have placenta previa early in pregnancy, it usually isn’t a problem. However, it can cause serious bleeding and other complications later in pregnancy.

Diagnosis and symptoms

The most common symptom of placenta previa is painless bleeding from the vagina during the second half of pregnancy. If you have spotting or bleeding during pregnancy, it’s important you call your provider right away. But, not all women with placenta previa have vaginal bleeding. In fact, about one-third of women with placenta previa don’t have this symptom. An ultrasound can usually pinpoint the placenta’s location to determine if you have placenta previa.

Is there treatment?

Treatment depends on how far along you are in your pregnancy, the seriousness of your bleeding and the health of you and your baby. The goal is to keep you pregnant as long as possible, but at any stage of pregnancy, a C-section may be necessary if you have dangerously heavy bleeding or if you and your baby are having problems.

How can I reduce my risk?

We don’t know how to prevent placenta previa, but you may be able to reduce your risk by not smoking or doing illicit drugs such as cocaine. If you have a healthy pregnancy, and there isn’t a medical reason for you to have a C-section, it’s best to let labor begin on its own. The more C-sections you have, the greater your risk of placenta previa.

As soon as my mom held me in her arms, she said she forgot all about the scary hours beforehand. She was so grateful that she had gone to the hospital when she did.

Remember, if you have spotting or bleeding at any point in your pregnancy, call your provider right away or go to the emergency room.
