Art for healing during pregnancy hospital stay
This study wants to see if being able to choose your own visual art to put up in your hospital room makes you feel more satisfied with your stay. If you are pregnant and staying in the antepartum unit, you may be able to help by choosing some art and filling out a short survey.
Albany, New YorkAges 18 years+ - NCT06859177Recruiting
Remote fetal monitoring trial for complicated pregnancies
This study tests if women with high-risk pregnancies can safely use a remote monitor at home instead of staying in the hospital. You would use a belly patch to send your baby's heart rate and your contractions to your care team.
Veldhoven, North BrabantAges 18 years+ - NCT07009704Recruiting
Glucose monitoring and support in pregnancy study
This study tests whether using a continuous glucose monitor (a small sensor that tracks your blood sugar) along with support from others can help prevent or manage high blood sugar during pregnancy. It is for pregnant women under 20 weeks who have certain risk factors for gestational diabetes.
Boston, MassachusettsAges 18–45 - NCT07135635Enrolling by invitation

Study of gut microbiome in weight-related pregnancy outcomes
This study looks at differences in the gut’s living microbes (microbiome) in people who are trying to conceive or are early in pregnancy, and how that may relate to pregnancy outcomes. It may help researchers understand whether microbiome changes are linked to healthier—or more complicated—pregnancies.
Rotterdam, South HollandAges 18–45 - NCT05870878Recruiting
