"need advice" ultrasound pictures

Kendra

I'm 30 weeks pregnant and I got my 20 week ultrasound done in July around 21 to 22 weeks! very clear to see her everything, could get very clear pictures of baby, but the three printed pictures I got where just awful I got a blurry foot which is the most noticeable picture, then I got a picture of the back of babys head(not much to see or show there), the other picture I don't even know what it is it's very unclear I think maybe the arm or leg but I'm not sure.. the lady gave me a CD and told me the heart beat was on there and more pictures it's the spine and two more unclear pictures of a small part of the baby I didn't get a picture of head and body like every other ultrasound! these is my first pregnancy and I just want a full picture of my baby (not to sound heartless and terrible) is it normal to only get pictures of random body parts? if not what do you suggest I do? any advice will help
