Private US

Hey guys

According to my to doc I am 10w4d, due date 12/22. I haven’t seen the baby since 6w1d so I paid to have private 2D scan today because I am that nervous first time mom. Boy am I glad I did it! I found a really awesome and affordable imaging place close by. See pic below. Sonographer shows due date of 12/16, which isn’t that far off. GA shows 11w3d, I am confused if I am 10 weeks or 11?? Also she thinks it’s a girl based on her experience but still way early. Any thought or advice is appreciated :)
