NT scan at 11 weeks 6 days?

KMLP

I moved my scan up a week because it worked better with my schedule.  The doctor said it could be anywhere from 11-13 weeks, but I was just wondering if anyone had trouble with the scan at around 11 weeks.  Hopefully, they will be able to get the measurements they need.  I have a tilted uterus, but I was able to have an abdominal ultrasound at 8 weeks with a full bladder.
