If you are pregnant, be alert for any vaginal bleeding. Sudden, painless vaginal bleeding may be the only symptom of placenta previa, a placenta that partially or fully covers the cervix.

If you have placenta previa and are not bleeding, it is important to follow certain precautions:

• Avoid all strenuous activities, such as running or lifting more than approximately 20 lb (9.1 kg).
• See a doctor immediately if you have any bleeding. Be sure that he or she knows you have placenta previa.
• Have a phone nearby at all times.
• Advise all health professionals who examine you that you must not have pelvic exams.
• Refrain from sexual intercourse after 28 weeks of pregnancy. Before 28 weeks, ask your health professional about any possible risks.
• Avoid inserting anything, such as tampons or vaginal douches, into the vagina.
• Be close to a hospital that can provide emergency care for both you and a sick or premature infant.

Call 911 or other emergency services right away if you have severe vaginal bleeding. Severe vaginal bleeding means you are passing blood clots and soaking through your usual pad each hour for 2 or more hours (you should not be using tampons).

Call your doctor now or go to the closest emergency room right away if you have any vaginal bleeding.

If you have had placenta previa

After you have had placenta previa, you may have questions about a future pregnancy. Based on the nature of your condition, your doctor will be able to answer your questions and address your concerns.

In very rare cases, placenta previa causes a stillbirth or newborn death. Should you experience such a loss, allow yourself time to grieve. Expect that your partner, children, and other family members may also be deeply affected. Consider meeting with a support group, reading about the experiences of other women, and talking to friends, a counselor, or a member of the clergy to help you and your family cope with your loss.
