Make a Reproductive Life Plan & Schedule a Preconception Doctor’s Visit:

Make a reproductive life plan to think about your goals for school, your job or career, and for other important things in your life. Then, think about how having children fits in with these goals. When you are ready, plan your pregnancy. Whether you are trying to have a baby, or are just thinking about it sometime in the near or distant future, it is never too early to start getting ready for pregnancy.

Women should see their health care provider BEFORE they get pregnant. This is called preconception care. Many birth defects occur in the very early weeks of pregnancy before a woman has missed her first menstrual period, so it is important that she see her doctor to discuss medical and family history before she conceives. This is especially important for women who have had a previous child with birth defects. Interconception care provides a unique opportunity to address specific risk factors that may have contributed to previous poor pregnancy outcomes.

Consume Enough Folic Acid:

If a woman has enough folic acid in her body before and during pregnancy, it can help prevent major birth defects of her baby’s brain and spine. These birth defects are called neural tube defects  or NTDs. Research shows that if all women of child bearing age consumed the recommended amount of folic acid, 70% of NTDs could be prevented.

Women who have had a previous NTD-affected pregnancy and are planning another pregnancy should consult their physician about consuming 4 milligrams (4,000 micrograms) of folic acid every day for NTD recurrence prevention. That is 10 times the recommended amount for most other women.

No smoking sign

Avoid Alcohol, Street Drugs, and Tobacco:

These substances can cause birth defects. Ideally, a woman should stop using these substances before she becomes pregnant, but it is never too late to quit.

No amount of alcohol is known to be safe for the developing fetus. Learn more information about alcohol consumption during pregnancy from the CDC.   

Street drugs such as cocaine and marijuana, when taken by a pregnant woman, are delivered to her unborn baby via the blood supply through the umbilical cord. These and most other illegal drugs pass easily to the fetus and therefore must be avoided.

Smoking may lower the oxygen available to the baby, which can cause the baby to grow more slowly and gain less weight in the womb. In the United States, about 1 in 8 women smokes during pregnancy.

Prevent Infections:

Germs that cause only mild or no symptoms at all in adults can be deadly to the unborn fetus. Women of childbearing age can avoid some of these by making sure that all of their immunizations are up-to-date before becoming pregnant. Other harmful germs and parasites can be avoided by using good hygiene.

Manage Medications:

Some medications are shown to be harmful to the unborn fetus. Others are necessary for a mother to remain healthy. In order to find out what medications you should and should not be taking, talk to your physician. Do not start or stop taking new medications (including over the counter and herbal remedies) without first talking with your physician.

Blood glucose test

Control Chronic Conditions:

Women who have conditions like diabetes, epilepsy, or obesity should talk to their health care provider about measures to take if they are considering pregnancy, or if they discover that they are pregnant. Sometimes better medication or a different dosage is recommended for treating the condition in pregnancy.

Eat Right and Maintain a Healthy Weight:

Getting enough folic acid and eating well balanced and nutritional meals provides a developing baby with the nutritional needs they need to grow properly.

Generally, women who are obese before pregnancy are at a higher risk for complications during their pregnancy. Additionally, the risk for some serious birth defects is increased in women who are obese. Talk with a doctor about ways to reach and maintain a healthy weight before and during your pregnancy.

Avoid other harmful substances:

Because most substances can pass through the placenta into the fetus' blood supply, mothers-to-be should avoid exposure to anything toxic. This includes fumes from strong household chemicals such as gasoline, paints, paint thinner, and pesticides; lead in some paints; and water from contaminated sources. You can look up health and safety information on common household products at the National Library of Medicine's Household Products Database, and you can call the Texas Teratogen Information Service at 1-855-884-7248 for more information.

National Institute for Occupational Safety and Health (NIOSH): Reproductive health and the workplace: This website provides information on workplace hazards that may pose a risk to male and female fertility, pregnancy, breastfeeding, and children’s health. Sub-pages provide information on what employers, workers, and healthcare providers can do to address reproductive hazards in the workplace. Guidance on reducing take-home exposure (chemicals carried into the home and car on skin, clothes, shoes, and hair) is also provided, along with information on personal protective equipment and special issues during pregnancy.

See a Doctor Regularly:

Even though you may feel healthy, it is important to see your doctor regularly. Doing this can help catch any complications early on. Certain women are at higher risk than others if they have already had a baby with a birth defect. Getting proper care can address any risk factors that may have contributed to poor pregnancy outcomes from a previous pregnancy.
