Measuring Ahead

So, my original due date was February 28, then it got changed to March 9th since he was measuring smaller. I had my last appointment at 28 weeks and was measuring at 29.5. Then I had a 4D ultrasound with a different doctor a few days later and they said he was measuring to be due February 28! Has anyone else gone through this and what outcome did you have?? Did you deliver closer to your original date? I feel like he's going to be here in February!
