So nervous for tomorrow

I'll be 12 weeks 5 days tomorrow  and I'm having my high risk ultrasound by the high risk OB. So far this pregnancy has been my best! No bleeding and no issues but  I'm so nervous! With my last pregnancy this was the ultrasound when we found he had a major heart defect. I'm praying all my baby girls organs are there and healthy and no heart problems. I have a good feeling about but still scared.
