First Ultrasound

I had my first ultrasound today. Everything is looking great! We were even able to see the yolk sac!
We were checking my quant levels last week and they more than doubled every 48 hours. This pregnancy seems to be right on track!
I just hope and pray that I have a healthy baby. 
I have had three miscarriages and gave birth to my daughter at 30 weeks in December, she died an hour after birth. (She had HypoPlastic Left Heart and Hydrops.)
I'm due the day before her first birthday! 
Has anyone else had an early ultrasound?
