Babys position has changed

Kristen

Ok I'm 11 weeks and 2 days exact. Baby is measuring exactly on time at 11 weeks 2 days. Went to a private scan today for ultrasound pics and Sneek peek DNA gender test. Well the baby's position has changed. I had an ultrasound at 9 weeks 1 day baby was facing opposite direction than the ultrasound today. I also went to the dr. At 10 weeks 1 day I'm high risk by the way and baby was measuring right on time not even a day off and was facing the same direction at my 9 week ultrasound. So why this week baby is facing a different direction. All 3 were abdominal scans so I'm so confused.
