Big baby!!!

So I'm pretty nervous! I'm due on 21st of January! And doctor has done an ultrasound at 37 weeks due to measuring large, to find that baby was 8lb 10oz but seem to think could be a pound heavier! I'm now 39 weeks of today and wondering how big baby currently is. Was told I have to have a c section and that they will call me and let me know when. I have only 1 week until my due date. Feel like I'm going to have a 11 pound 👶🏻 😩 any mumma's have similar estimates???
