    Understanding a Multiple Pregnancy

    A multiple pregnancy means you’re pregnant with two or more babies. It can be both exciting and scary. You might wonder how this pregnancy will be different. You may want to know how it will affect your health. And you will want to learn how it can affect the health of your babies.

    A multiple pregnancy can happen if you use fertility treatment. This is medical help to have a baby. Or it can happen naturally. Twins may run in the family. A multiple pregnancy is often found early. Then you can get extra prenatal care.

    Prenatal care for a multiple pregnancy

    A multiple pregnancy is a high-risk pregnancy. This means it has a higher risk for problems. Prenatal care will need to include:

    • More prenatal visits. This helps your healthcare provider closely watch your health and the health of your babies. It’s important to check their growth in the womb. Your provider will watch for problems. They will check your weight and nutrition.

    • Repeated ultrasounds. These are used to check the growth of the babies. They check the volume of amniotic fluid. These tests start in your second trimester. You may have an ultrasound every 4 to 6 weeks.

    • Tests to check your health. You may have earlier blood sugar tests. This is to see if you have gestational diabetes. You may be tested earlier for iron-deficiency anemia. Your provider will also check your blood pressure often.

    • Tests to check the health of the babies. You may have amniocentesis. Or you may have chorionic villus sampling (CVS). These are done to test for birth defects. You may have a nonstress test. This is to check the heart rates of the babies.

    • Preparing for birth. A multiple pregnancy raises the risk for preterm birth. It raises the risk for cesarean section (C-section). It’s important to talk about these with your healthcare provider.

    At prenatal visits, you’ll need guidance on:

    • Nutrition

    • Prenatal vitamins

    • Activity

    • Expected weight gain
