BABYS WEIGHTS FROM SCANS..

I had a growth scan at 27 Weeks & 4 days, I got told she weighs 3lbs already, I'm only tiny & in very very uncomfortable, she even feels big, when the midwife felt my belly she said I've got a good sized baby growing😂🙈! Can people tell me if this is a normal weight cus when I've googled it they should only weigh 3lbs after 31 weeks? Has anyone else had growth scans or any other scan around the 27-32 Weeks and can tell me what there baby weighed?xxx
