PregSource®: Crowdsourcing to Understand Pregnancy

PregSource logoThe PregSource® project has ended. NICHD and the PregSource® team thank all who participated in the study.

NICHD will add the de-identified PregSource® data to the NICHD Data and Specimen Hub (DASH) to enable additional research and analyses.


The PregSource® research project sought to improve knowledge about pregnancy by collecting information directly from pregnant people. Gathering this first-hand knowledge through confidential, online questionnaires was meant to help researchers learn how people from a variety of backgrounds experienced pregnancy, and then use that information to improve care.

People who joined the PregSource® project could track their pregnancies, share their health information with providers, and see how their experiences differed from others in the study. The questionnaires addressed nausea, mood, weight gain, labor, delivery, feeding, medication use, and infancy.

Topic Areas

PregSource® asked questions about:

  • Background (such as age and education level)
  • Pregnancy experiences (such as sleep patterns and nausea/vomiting)
  • Overall health (such as any pre-pregnancy medical conditions or pregnancy-related problems)
  • Labor and delivery (such as length of labor and type of birth)
  • Infant health (such as weight at birth)

Researchers will continue to review the information submitted by pregnant people to spot trends, similarities, and differences and to answer research questions.
