Confused - is it an American thing?

Hi Ladies, I'm 5w6d pregnant - yay! I live in England and have my first midwife appointment on 14th Jan (I am not 100% sure what this entails)...but my first scan/ultrasound will not be until I'm 12 weeks...I was just wondering why/how some ladies are going for scans at 7w, etc? Is this normal practice in America?
