Panorama Re-take :(

I had the blood draw a week ago today. I was 14 weeks. The nurse called today and said they got the results, only there weren't any results because they weren't able to get enough of the fetal dna. So now I go back next Tuesday for a re-draw. I was really surprised this happened at 14 weeks since the test says as early as 9 weeks. Anybody else had this happen? Hope this doesn't happen again. I'll be 16 weeks when I get the re-draw done.
