Ultrasounds?

Today my pregnancy was confirmed at the woman’s health clinic with their tests & they scheduled me an ultrasound for 7 weeks instead of 10 weeks like they originally do here, but since I had a miscarriage a month prior to this pregnancy that is why they want to do it sooner. What did your ultrasound look like around 7 weeks? I had my first ultrasound when I was 9 weeks with my first born. Will this one look pretty much the same or less visible? I’m so nervous!
