I went last week to the doctor pick up some results they had did the blood test on me to see if the baby had Down Syndrome well my results came back positive but nobody in my family or in my boyfriend family has Down syndrome everyday I look at sonograms of baby with Down syndrome see if I can find something similar to my sonogram but I can't I don't see it in my baby and I feel it in my heart that my baby is healthy I have a appointment Monday for deeper examination to determine if it's a yes or a No can someone please take a look at my sonogram and compare it please thank you
