Researchers want to understand how sleep problems during pregnancy might affect the health of your heart and blood vessels. This observational study will follow you at two different points in your pregnancy to measure your sleep quality, physical activity, and cardiovascular health through simple tests and monitoring devices.
Sleep problems are common in pregnancy, but doctors don't fully understand how they affect a pregnant person's heart and blood vessel health. This study aims to fill that gap so that healthcare providers can better identify and support pregnant people who may be at risk.

You would visit the research lab twice during your pregnancy (once around weeks 20-24 and again around weeks 28-36). At each visit, you'll spend 8 days wearing activity trackers, keeping a sleep diary, completing questionnaires, and having one night of home sleep monitoring. You'll also have a lab visit for a blood draw and heart ultrasound to measure your cardiovascular health. After your baby is born, you'll complete a brief follow-up survey.
