Ultra sounds

So I see everyone getting ultra sounds at the end of their first trimester and it's awesome but am I the only one that my doctor is making me wait til 20weeks?! She said there is no need for an ultra sound unless they believe something is wrong. Since we heard a strong heart beat at 10weeks 1day she said there is nothing to worry about. I'm now 11weeks an 1day an I just want to see my baby :(
