First ultrasound on the 21st next Tuesday

Marie • 20 and I’m married to the love of my life. First baby born 02/13/2021! Que❤️🍼

I will be 8 weeks 5 days on the first ultrasound. What should I expect? They said my husband gets to come with me. First pregnancy also. And I’m in the U.S. if that helps. Just a very worry full momma here.
