baby measuring over weight?

I'm 25 weeks pregnant I've only gained 10 pounds which is normal I workout often . However when I went to my sonogram the lady said my baby girl was a chunker .lol. I guess she is measuring 2 weeks ahead . Does this mean I will have a big baby or who knows ? Just wondering anyone else baby is a "chunker " πŸŽ€πŸ‘ΆπŸ»
