First ultrasound today! Have to go back in two weeks though.

Is it normal to go back in two weeks? Im 7 weeks 3 days and I was measuring exactly to my due date and I’ll be 9 weeks and 1 day when I go back. My OB said she likes to do it for the reassurance for me and my partner but I’m starting to overthink it. Also hearing the heartbeat today was surreal!
