Participants will be eligible for a daily lottery if they have weighed themselves in the previous day on the e-scale. For each day of the study, participants will be informed of the study's randomly-generated winning lottery number and their winnings ($0, $2, $15 or not eligible for lottery due to lack of weighing). Participants will receive $14 per month if they have gained within the recommended monthly range for their BMI category. Otherwise, participants will be specifically notified that they would have received $14 had they had gained within the recommended range for the month, drawing on research showing that loss aversion can be motivating.
Participants will be eligible for a daily lottery if they have weighed themselves in the previous day on the e-scale. For each day of the study, participants will be informed of the study's randomly-generated winning lottery number and their winnings if any. Participants will be given the IOM GWG recommendation based on their body mass index at randomization, adjusted for data collection at 36 weeks. If they achieve the goal at 36 weeks, they will receive $112 after the data collection visit. Participants will be asked to engage in 150 minutes of exercise each week based on the guideline from the ACOG. They will receive $3.50 if they meet their activity goal for the week. Otherwise, they will be notified that they would have received $3.50 had they meet their activity goal.

Participants randomized to an arm that contains the self-weighing (certain loss) component will have a balance of $3.50 at the beginning of each week of the the study and each day that they do not weigh, $0.50 will be subtracted from this account.
