Ultrasound at 7 weeks?

First time poster, long time lurker. I will be 7 weeks tomorrow and am going in for my first appointment. My husband and I have read conflicting things about whether or not they will do an ultrasound at 7 weeks and I am just wondering if any of you have any advice? When I set my appointment they said they would “get me scheduled for an ultrasound” after this first appointment but I’m just really hoping they will go ahead and do one. We are first time parents who have been extremely nervous and just want to hear a heartbeat. Thanks!
