Cherii, I have to agree with what River has said. Ultrasounds are notorius for being out. I think the best thing you can do for yourself is to get any idea out of your head that your baby is big. At this stage of your pregnancy that is totally normal

I had a 4 d scan at 30 weeks of my last pregnancy. It said bub weighed approx 1735gms. She was born weighing 3 kgs at 37 weeks.

Starving yourself or even dieting will have no effect on your babies size at all. Yes, this is the time that babies grow the most, and they are only gaining fat now, but no matter how little you eat it won't slow down bub's growth.

Enjoy the fact that you are having a healthy baby and put off thoughts of an induction merely for a "maybe that she's big"

Being induced before bub is ready is also setting yourself up for a "failed induction" leading to more intervention and a c section is likely. I am not saying that it will happen, just that it is a high possibility if bub and your body is not ready.

Read up and do some research hun. Information is your best thing to gather. It's something that can make all the differance.

Goodluck I look forward to reading your birth story
