Harmony Test results?

Be

I just got a call from my doctor to tell me my harmony test results. The baby is perfectly healthy and is low risk in every category. However the doctor said they weren’t able to give me a result for the sex chromosome abnormalities. I can’t find much information on this. Having a section of the test be neither positive nor negative is giving me anxiety. She told me there may not have been enough DNA percentage to make a clear statement but that doesn’t seem likely with results on everything else including the gender. She said it was strange but the conclusion is that the baby is healthy. (So grateful for this) I was 10 weeks and 2 days when I got the test done it that makes a difference. If anyone had this problem and has any information please let me know! Thanks
