NIPT test bummer

I just turned 35, my husband and I decided to start a family...I did the NIPT testing because of my age and it came back at increased risk of 5-p deletion syndrome, a super rare michrocromosomal deletion that happens in 1/50000 pregnancies!!!! Could this totally be a false positive?? I am having an amnio on Dec. 7th, I'm super nervous and it's hard to have my belly grow for so long and just keep waiting to find out for sure. I'm 14 weeks... my husband and I are super healthy, no chromosomal diseases or history on either side. Do we just have the worst luck?? I'm so torn and it's hard to be happy and pregnant right now. Has anyone had similar results? All other tests and ultrasounds are totally normal. I'm tripping out....
