The main purpose of this legislation is to create a centralized online resource for expecting mothers, called "pregnancy.gov." This website aims to provide valuable information and resources tailored to the needs of pregnant women based on their ZIP codes. The goal is to enhance access to relevant services and support during pregnancy and early parenting. Key provisions of the legislation include the requirement for the Secretary of Health and Human Services to establish and maintain the pregnancy.gov website within one year of the law's enactment.
