Summary

This study tests whether a smart ring (Oura Ring) can be used to monitor physical activity and sleep in healthy pregnant women from the first to third trimester. Researchers will assess how acceptable and easy the ring is to use, and whether maternal factors like age, weight gain, and stress relate to activity and sleep patterns. The goal is to see if wearable technology can provide useful health insights during pregnancy.
