NT Scan at almost 14 weeks

I just got called with the results of my NT scan and blood work that I got done around 14 weeks I am now 15 weeks. At the appointment the Doctor said the fluid was 2.8 I am 26 so he said that that number is a high normal but they usually don't worry unless the number is 3.5 or higher and because I am so young I should be fine also the baby's nasal bone was very pronounced and obviously seen. I got the results though and the scan with my blood results shows that I have a 1:13 chance of having a baby with Down Syndrome. The NT scan I have read is not a factual result it is more a statistical result and the accuracy is 40%. I am kind of annoyed by the woman that called me with the results because she told me the odds of me having a normal baby are 3% well... She has some nerve to tell me without fact that the likelihood of me having a normal baby is so low but told me I have a 7% chance of having a baby with Down syndrome. She made me cry and I got really overwhelmed, worried and stressed after the phone call. I just feel like she should have been a little more gentle with discussing it and reassured me that these test aren't a 100% and just said if I want more I can go for the new blood test that shows chromosomal abnormalities. Instead she pretty much told me "you are going to have a baby with Down syndrome" which she or anyone else can't determine that without the blood test or other tests like an amnio. Also she kept talking to me in a pity voice and going, "I know this is very difficult to hear" like she was giving me a definite result and there was no chance that I would have a normal healthy baby. The NT scan doesn't scan for any chromosome issues so how can they know for sure my baby will have a problem. The test just gives you odds that your baby may have a problem. I read in online forums that some woman get a 1:3 chance and have fully healthy babies and some get 1:4,000 chance and their baby is born with Down syndrome. I think the NT scan is bull shit and it scares parents into paying for further testing. My cousin was told her baby was at very high risk and when her daughter was born she was a happy healthy baby. Regardless I would not terminate the pregnancy because regardless this is my child but at the same time I want to know what to expect. I may do the blood test just to get peace of mind. Has anyone else gotten similar results  and ended up with a healthy baby?
