About this trial
The researchers would like to know how long pregnant women spend in different positions during the night - and how often women change positions - across pregnancy. The researchers also want to see if the sleep monitor is able to improve sleep behaviors

Treatment groups
Trial outcomes
Primary outcomes
Proportion of sleep time spent in the supine position as measured by the Pregnancy Coach
Will be conducted using the naturalistic arm (deactivated device). Simple descriptive statistics to report the average number of minutes and the average proportion of supine sleep per week.
Secondary outcomes
Proportion of sleep time spent with objective snoring as indicated by the Pregnancy Coach
Will be conducted using the naturalistic arm (deactivated device). Proportion of time will be determined during each gestational week.
Proportion of participants where their 'going to sleep' position was the same as their dominant sleep position
Will be conducted using the naturalistic arm (deactivated device). We will determine whether the "going to sleep" position during each gestational week is predictive of the most dominant sleep position.
Percentage of sleep position changes following alert from Pregnancy Coach
Will be conducted using the intervention arm (active device). Percentage of sleep position changes in response to an alert from the Pregnancy Coach will be reported for each gestational week.
