Panarama test issues

Heather
So 3 weeks ago I had the panarama genetic testing done well 7 days later they said there wasn't enough fetal DNA so I had to redo it. Well I redid it 7 days ago and today they called to tell me the DNA was too messy to do any testing and asked me if I'd ever had a bone marrow transplant or if it was a donor egg. So once again I get to retake it. I'm panicking what if this means there is something wrong. Anyone ever heard of this?
