Study Arms (1)

Daily Weight Tracking

OTHER

Participants will be provided with a wireless Bluetooth-enabled bathroom scale with instructions for connecting it to their home wifi network or phone using Bluetooth and a mobile app, and will also be walked through creating an anonymous study account for app access. They will be asked to track their weight daily for 6 weeks and will receive weekly feedback on weight gain trajectories along with nutrition or physical activity messages for healthy pregnancy weight gain.

Behavioral: Daily Weight Tracking
