30 week growth scan, HELP

Katie

My game plan from the beginning was an unmedicated birth, and it still is! But today at our 30 week growth skating we were all shocked at how big he is measuring. His head is higher than the 98th percentile and overall they're estimating him at 4 lb 6 oz already. My doctor is willing to let me try whatever I want to try but I just wanted to know what everyone else's scans looked like and then what their baby came out weighing.
