If you have any chronic medical problems (such as high blood pressure, kidney problems, or diabetes), talk to your provider before trying to get pregnant.

See a prenatal provider before trying to get pregnant or early in the pregnancy. This can help prevent, or detect and control health risks to the mother and unborn baby during pregnancy.

Talk to your provider if you are planning to get pregnant within a year of your or your partner's traveling abroad. This is especially important if traveling to areas where viral or bacterial infections could affect the health of an unborn baby.

Men need to be careful, too. Smoking and alcohol may cause problems with the unborn baby. Smoking, alcohol, and marijuana use have also been shown to lower sperm counts.

Is Your Pregnancy High Risk?

You may have a high-risk pregnancy if you:

The correct answer is any of the above. Work with your doctor to manage any health problems before you get pregnant. Ask for advice on how to quit any habits such as smoking that may put your baby at risk. Getting regular prenatal care is the best way to have a healthy baby.

Which pregnancy problems can put your baby at risk?

The correct answer is all of the above. If you have a high-risk pregnancy, your doctor may want to see you more often and do more tests while you are pregnant. That way, your doctor can treat any health problems early on before they affect your baby.

If you are carrying twins or triplets, you have a high-risk pregnancy.

The correct answer is true. Carrying more than one baby puts more of a strain on your body and your uterus. It puts you at a greater risk for health problems. For example, you are also more likely to deliver before your 38th week (preterm delivery).

Your doctor can prevent health problems from blood mismatches.

The correct answer is true. Rh incompatibility occurs when a pregnant woman has Rh-negative blood and her baby has Rh-positive blood. It can cause mild to severe -- and even deadly -- health problems. Fortunately, any problems can be prevented by injecting the mother with a medicine called RH immune globulin.  

Which of the following is true about gestational diabetes?

The correct answer is all of the above. Gestational diabetes occurs because pregnancy hormones keep insulin from doing its job. This causes sugar (glucose) to build up in your blood. It usually goes away after you give birth, but you are at risk for diabetes later in life. Your doctor can help you manage diabetes and prevent problems.

The only way to cure preeclampsia is by having your baby.

The correct answer is true. Preeclampsia is high blood pressure and high protein in your urine that occur during pregnancy. Symptoms may include swelling of the hands and face and sudden weight gain over 1-2 days or more than 2 pounds a week. Tell your health care provider right away if you notice unusual swelling or weight gain.

Treatment for preeclampsia includes:

The correct answer is all of the above. If your baby still has a lot of growing to do and you have mild preeclampsia, you can manage the disease at home until your baby has a good chance of surviving after birth. If needed, your doctor may have you stay in the hospital so you and your baby can be closely watched for any problems.

You can prevent preeclampsia.

<p>The correct answer is true. The American College of Obstetrician and Gynecologists recommends low-dose aspirin therapy for women at high risk of preeclampsia. These risk factors include:</p><p><ul><li>History of preeclampsia</li><li>Having twins or more </li><li>History of diabetes, high blood pressure, or kidney disease</li><li>Having an autoimmune disease, such as lupus</li></ul></p> <p>Anyone can develop preeclampsia, so be sure to see your doctor for regular prenatal care.</p>

Most babies born at 28 weeks don't survive.

The correct answer is false. At least 90% of babies who are born at 28 weeks survive. Being born early used to cause most infant deaths. Better medical care has helped more premature babies survive. The closer a pregnancy gets to full term, the greater the chance the baby will live.

Getting early and good prenatal care reduces the chance of premature birth and other problems.

<p>The correct answer is true. The best ways to prevent an early birth are to:</p> <ul><li>Be in good health before getting pregnant</li><li>Get prenatal care as early as possible in the pregnancy</li><li>Continue to get prenatal care until the baby is born</li></ul>
