8 weeks and so nervous for my first Ultrasound next week

Anyone else anxious/ nervous about waiting for their first ultrasound appointment. I'm 8 weeks as of today so my ultrasound will be at 9 weeks and I'm terrified their won't be a heartbeat. I hope I don't sound crazy or weird saying that?? But it's honestly in the back of my mind. I think I keep thinking about it because my symptoms have been so mild compared to other people I know :/ I know I should feel lucky to not have symptoms really which don't get me wrong I do! But it also terrifies at the same time. I have been waiting for this moment and thinking about my future with my little peanut and it is just driving me crazy waiting!!!!! 😭
