Well done on controlling your GD so well, hun! I can't believe you're already 36 weeks. Where has that time gone??

I guess you need to have a big discussion with your ob, but this is good news for you being allowed to continue the pg and go into labour naturally surely. FWIW my u/s at 37 weeks was wrong about baby's weight too - it suggested over 6 lbs at 37 weeks and she was born two weeks later weighing a mere 5 lbs 10 oz. So if anything, the u/s might even be underestimating your LO's weight.

GL with your next appt.
