Anyone have to move their c-section?

So I am technically by what we’re going off of 33 weeks pregnant but this pass Wednesday I came in to my appointment (32 weeks). Now I just started my every two weeks come in appointments but now next week I have another appointment and we are having an ultrasound done because I am measuring to be 35 weeks and some odd days. Dr is expecting him to be a very large baby but the problem is at our 22 weeks ultrasound he was measuring ahead then too but they weren’t concerned. Now it seems like we may have to change the C-section date. I also at the end of each pregnancy (40 weeks) weighed in at 160ish but I am already at 165. Has anyone else had this experience? Or experienced similar?
