7w3d but measuring 5w5d???

A

I went for my first ultrasound today assuming that I was 7 weeks and 3 days. But baby is measuring 5 weeks 5 days. Does this ultrasound look normal or concerning to anyone? My dr said I have absolutely nothing to worry about but I can’t help but worry until I go back in two weeks 🤦🏼‍♀️
