5 weeks 5 days Pregnant

Hey, I had my first ultrasound today. The baby is the white spot by the circle. The heartbeat was 125 and we could see it on the screen. I thought I was like 7 weeks atleast. With my son who will be 1 April 14th didn't get a positive tell 6 weeks and a ultrasound tell 10. Did anyone else's ultrasound look like mine just a dot? Heart beat was 125. What were everyone's gender with 125 heartbeat? I know you can't determine gender that way, just curious. Thanks ladies! :)
