6 week ultrasound

SD

I have an ultrasound on Friday (I am going to be 6w4d then), and while I’ve done this before (my last was 6w6d) I still feel nervous. Would any of you mamas be willing to share your US experiences at 6 weeks? I know that if we don’t see a heart beat or much that I shouldn’t freak out, but still, some positivity would really tide me over and make my day.
