Possible Cystic Hygroma?

I had my first OB appt this morning. I am 11weeks 3days according to the measurements they got. Our baby moved like a worm the whole time during the ultrasound so they couldn't even get the baby to be on it's side so they had to measure it differently. However, when the OB saw me she said there was and increase NT and they were worried about Downs or any abnormalities. She referred me to a high risk OB and did some blood work. The appointment with the high risk OB has not been set yet. They don't have the measurement of the thickening but I got this pics from the CD of the ultrasound. I am pretty down and sad about it but loves the baby even more. Any of you had this experience and ended up having a normal healthy baby? Any input would be appreciated. Thank you.
