First Ultrasound

I had my first ultrasound this morning! Saw the baby, yolk sack and heard the heartbeat! So happy but they did move back my due date to 11/22. Based on my LMP I was 7 weeks today but turns out 6 weeks 4 days. A little sad about going backwards, I just want to be 12 weeks already!! 💕💗💕Hdas this happened to anyone else?
