 The first contact to the participant will be made by phone at about 12-14 weeks of gestation, when, as a part of routine care, all mentally vulnerable pregnant women are contacted by a midwife from the Department of Obstetrics, Rigshospitalet. In this interview, the pregnant woman will be given brief information about the trial. If the woman is interested in further information, written participant information about the trial will be send. If the pregnant woman would like to participate in the project, an appointment for a personal meeting is made, where the participant is given more information about the project before written, informed consent is obtained and randomization can take place.
