4D ultrasound

We did a 4D ultrasound video and photos yesterday and it wAs amazing to see our little man's facial features! Looks a lot like me. They found out I have anterior placenta, which concerns me but the little bit of research I did yesterday said its not necessarily a huge problem but my OBGYN isn't aware of it yet. Anyone have any experience with that? Can't wait to meet our son October 16 :)
