Measuring A Week Ahead.

I just had my ultrasound yesterday. And the tech said if I was sure of my due date. I said yes. I’m supposed to be 13w2d. She said however, that I’m measuring at 14w2d. She then said she wasn’t gonna put that on my paperwork. So to just stick with my EDD. That it might just be a bigger baby. Then asked me if my babies have been been big. But my biggest out of the four (im on baby #5) was 7lbs.

My question is: has anyone experienced this? Have they gone into labor the week before they were due? Thoughts...
