“Measuring ahead”

Hi friends!! So I am currently 28 weeks today, but at my last appointment a week ago they told me that he was weighing about 3lbs 3 oz and is in the 97th percentile! (At 27 weeks and a day) we happened to do my glucose test also that day and I passed with normal blood sugar. I eat healthy and workout at least 5 days a week and have gained about 20 lbs so far. She tells me just watch my added sugar but I just think it’s genetics! She also told me that some women opt for a c section depending on when I get further along if he is still measuring bigger and I don’t want to do that unless it’s absolutely necessary for their health or mine! I was just wondering if anyone else had an experience like this and what their outcome was?? I have heard many women also say that their baby was not as big as they were estimating (obviously I know it’s just an educated guess). Thanks in advance!!😊
