Congratulations on your pregnancy!to answer some of your questions. 1. You and your partner will be asked questions about your family medical history. So it's about your parents, brothers and sisters. 2. You can bring a urine sample or you can wait til you get there sterile containers are available 3.OH will be allowed for most of it I think though when they take your history they bring you in privately 4. Normally there is a 12 week scan (booking scan) OH is allowed in for that. Hope that helps x
