I went to a scan they said I was 6 weeks 3 days and then a scan at a week late measiring 7 weeks 4 days both with yolk and sac and a heartbeat. I the went 12 days late they said I was measiring 7 weeks 5 days so had grown by 1 day with a yolk and sac but no heartbeat. I don't know what to would you trust them and for a d and c or would you get another opinion ask for another scan ..thanks all xx
