I went in for an ultrasound at 6 weeks 4 days and all the doctor saw was the gestational sac. She explaned that she has had patients that did not see their baby, went in a week later and saw the baby with a heartbeat. She also said that there is a possibility it is a blighted ovum. Have any of you went in for an ultrasound didn't see your baby but saw him or her at a later date? I have not had any bleeding or any symptoms of a miscarriage and the one symptom of pregnancy I do have is really sore sensitive breast. This is my second child, my first is a happy healthy 3 year old.
