US, white dots in the heart, short nose

I just had my specialist appointment today to get all the organs of my baby girl checked. I was so happy seeing her again boxing like crazy.

But then the doc found two white dots in the heart and said that the bone in the nose is a bit to short. It could be signs of Trisomie 21.

I know the chances are still very low but I am so upset.

I do not know what to do. I could do a blood test, but they are very expensive and furthermore... what should I do with the answer? What if it is pregnant?

My fiance is very supportive saying it does not matter at all. He is just happy about our first child. But we want to build up a life, buy a place to live at some point, and I do not even have family close around.

Anyone else struggling with these thoughts?
