Sonagram of the baby - 10 weeks

I went to Dr. O's for a routine checkup and my 10-week ultrasound.  I already had an ultrasound at 6 weeks, but at the time it was the size of a grain of rice. Today we could clearly see the baby's body flipping around. It would not stay still long enough for a photo.  The pics were taken while it was in mid-flip. I also had blood drawn for genetic testing and the nurse asked if I was going to have twins. I told her that I only saw one baby in there so I don't think so.
