Recruitment {15}
Participants will be identified and recruited through the P3 Cohort, which will engage participants through ultrasound clinics, outpatient obstetric clinics, obstetrical triage, and advertising in the community. An informational postcard will be shared by clinic staff with potential participants, who will then be able to self-refer by providing their contact information to be contacted by a member of the P3 study team. Online advertising will contain a link to register for more information about the study, and participants will subsequently be contacted by the study team.
