First ultrasound

I'm kind of nervous for my first ultrasound (I'm 11wk+2days) because I've heard stories about people not finding a heartbeat etc. I assume all is well because I do seem to be getting a bit of a belly but I have no symptoms other than sore boobs all the time and bloat. And I haven't been being too careful except for heavy lifting.

Also wondering if there is any questions I should be asking at the ultrasound? This is my first pregnancy so I'm not sure what to expect. Any advice/positive experiences would be helpful thanks guys!
