Possible down syndrome?!


I had my anatomy scan yesterday and they told me that my babys nose looks like it is measuring behind. I cant remember the measurements he was telling me because I was kind of taken off guard. The doctor said that having nasal bones that are "delayed" can be an indicator of down syndrome. I have been crying all day yesterday stressing out over my little baby. I honestly do mind if my baby has downs, what I'm worried about is all the medical problems that may come along with it. I didnt get the genetic screening done yet which they said I can still do (I have a prenatal appointment thursday so I will ask my doctor if I have get that done). I just want to know for sure if my baby has it or not so I can prepare myself to be the best mother I can for my little guy. Have any of you ladies gone through this?! Advice?
