too big!?

Sophia
Okay, so last night I was at L&D for possible leakage of my amniotic sac (I'm only 30 weeks and all tests came back negative. I have no infection, and my water didn't break) but they did do an ultrasound and when they did they said my baby girl weighed 3lbs 11oz!! At just 30 weeks?? Has anyone been told they were going to have a big baby but turned out to be regular 7-8lbs? I am hoping I can talk them into an ultrasound at 36 weeks to see how much she weighs and if already 7-8lbs talk about a possible induction. Anyone have this??
