Ultrasound at 5wks+6days, anyone?

RiRi , P & PJ’s Mom 💗💖💙
I get one next Friday to hear my baby's heartbeat and see it at 5 weeks and 6 days. The doctor calculated my HCGs and I thinks it will be high enough by then. 
My question is won't I find out exactly where I'm at that day in my pregnancy so won't that be too early to see and hear anything, I ovulated on October 5th?
