Really nothing to worry about. My first measured "ahead" as well and they estimated crazy numbers and whatnot for him and he was 8 lbs. He's 9 today and totally healthy. He's a little on the thin side according to his pediatrician but that's it lol
Type 1 diabetic here, my son measured ahead although sugars were in normal range, and my high risk doctors had me terrified he was going to be a monster lol. They told me he was measuring close to 10 pounds at 37 weeks. I ended up having a c-section out of fear of him getting stuck. He came out 7 pounds 15 ounces at 38 weeks 🙃 a lot of the time I feel like it’s not nearly as accurate as they say. Try not to worry yourself!
It means nothing. My daughter and my belly measured 2 weeks ahead from 20w to the end of my pregnancy. She was born at 40w4d and weighed 7lb1oz
