Baby measuring large, but fundal height normal

Angela

I cannot seem to find anyone who has been in the same boat as me or had a similar situation. I'm currently 36w and my fundal height is measuring 36w as well. However, my baby boy is measuring 39w. He's been measuring 3w ahead since 22 weeks. He is in the 98th percentile. I don't have GD and I'm not obese. It's just genetics (husband is 6'4" and was a 9lb+ baby). My first was a girl, born at 38 weeks via csection (bucornuate uterus and I went into labor early). Has anyone ever had a baby measuring several weeks ahead despite fundal height being on track? What was the outcome?
