Anatomy scan

Jessica

I just received the results from my anatomy scan, and the physician said that my baby is measuring a little smaller than most babies. I’m 20weeks 5 days and the baby is measuring at 19weeks 5days. Also, she stated that I have a marginal placenta, meaning the cord is attached on the side of my placenta vs in the middle. Can any one please give me some insight to what this means danger wise? Will my baby then have complications due the placenta placement? Has any one had this and everything turn out ok?
