Big baby at 34 weeks ultrasound

I had a ultrasound last week at 34 weeks. My sweet baby Elora is already 5 lbs 13 oz. With 6 weeks left I'm wondering if she will be really big at birth. Im due on 9/29. This is my third girl. My first was almost 7 lbs at birth and my second was 8 lbs 7 oz. I'm not freaking out but I'd prefer not to have a 10+ lb baby. I know it's wishful thinking but maybe she will come early. I would only want that If she ready though. Just wanted to get some of your thoughts.
