Placenta Previa

Back to Document

by Rosenblum L


The doctor will ask about your symptoms and medical history. A physical exam will be done. A pelvic exam will not be done if placenta previa is a possibility. A pelvic exam may cause bleeding. Instead, an ultrasound will be done through the vagina or abdomen to view the placenta in the uterus. If placenta previa is detected early in pregnancy, with or without bleeding, another ultrasound will be done during the third trimester to be sure it has resolved.
If you had cesarean section in the past, and the ultrasound indicates a potential problem with the placenta, your doctor may recommend an MRI scan.
