Hi mama, don't worry, third trimester ultrasound weights can swing quite a bit, so those two readings might both be off the mark! From what I hear, estimates are usually within 15% above or below baby's actual weight, especially near the end of pregnancy, so the difference you're seeing isn't unusual at all. My neighbour had her scan show her baby at almost 7 pounds, but baby came out at 5 pounds 10 ounces, so the ultrasound can definitely be out either way. The thing is, as baby gets bigger and there's less amniotic fluid, it gets trickier for the machine to get an accurate measurement, and positioning matters a lot too.
That said, your doctor will have the full picture, they'll look at your fundal height, how you're carrying, and your overall health pattern, not just one number. It's worth bringing both those ultrasound reports to your next appointment and asking your doctor or specialist to explain what they're seeing, since they know your case best and can give you the reassurance you need. Wishing you a smooth delivery ahead!
