Cell free DNA test...is my baby even alive?

I took a gender test called Cell Free DNA test almost 2 weeks ago and the results came in today a d literally all it said was that i needed to retest because "not enough fetal DNA found". Does this not sound totally morbid or is it just me? I'm 12 weeks 1 day today ans i tested at 10 weeks 3 days and my ultrasound is in a couple of days. All i can think is that i suffered a missed miscarriage and I can't stop crying. I'm praying for a healthy 13 week baby on mondays ultrasound. Has anyone had this test performed and had the same result????
