Return ultrasound visit.

Jessica
On Friday I had my 19w ultrasound and found out im having a boy! The ultrasound went good. She told me everything was measuring good but my little one kept moving all around. She got some good pictures or his heart. Said the arteries looked really good and so did all four chambers but she was trying to get more pictures and he kept moving. Heart beat wad also good. But now I have to go back in 2 weeks for another scan to get the images that the doctor would like to see. At first I wasnt that concerned but now im wondering if something is wrong with him.. any experience?
