Due date changed and baby measuring big....

So I thought I was 33 weeks and due July 17th, but my doctor looked at my chart today, and said that my 14 week ultrasound showed that I should be 34 weeks and due July 11th.....

Also, my growth scan came back, saying that baby girl is measuring in the 87th percentile and they are guessing she will be 8lbs 15oz when born or possibly bigger....My fundal height is measuring at 40 weeks too apparently.

Has anyone else gone through this, and the doctors been wrong and you’ve had a smaller baby than they expected? This is my first baby and I am so scared of delivering a huge baby lol 🙈😂
