Baby’s Weight!

I am 33 wks. Today I had a growth scan, due to medical history I am monitored often and will have a lot more ultrasounds. Today she said that baby’s weight is estimated at 3lbs 15oz. I know these aren’t always exact. I may have to deliver early due to high blood pressure. In others experience, or other woman that have had multiple children. How accurate were the weight estimations for your babies? Just hoping she’s actually around that weight if not more!
