NT prominent ?

FTM had 12 week scan and the tech said the neck has fluid around it and the fold is prominent. She didn’t give me a measurement she said she was going to referrer me to fetal medicine unit. I’m 11 weeks and my family are telling me it could be because baby was moving around or still developing. I looked up what it means and it could mean downs, I have booked a NIPT test to ease my mind but still don’t know how to think. Has anyone had this and it turned out to be nothing ?
