5 Tips for a Healthy Pregnancy:

For women who are planning to get pregnant or have recently learned the news that they are, here are some recommendations.

1. Take 400 micrograms (mcg) of folic acid every day for at least 1 month before getting pregnant to help prevent birth defects, the U.S. Centers for Disease Control and Prevention says.

2. Stop smoking and drinking alcohol.

3. If you have a medical condition, be sure it is under control. Some conditions include asthma, diabetes, oral health, obesity, or epilepsy. Also be sure that your vaccinations are up to date.

4. Talk to a health care professional about any over-the-counter and prescription medicines you are taking. These include dietary or herbal supplements.

5. Avoid contact with toxic substances or materials that could cause infection at work and at home. Stay away from chemicals and cat or rodent feces.
