Any January 17 mommies measuring ahead by WEEKS? They're saying my edd is 1/16/17 but baby is in 97th percentile according to 20 weeks scan and has since 12 weeks measured ahead 3 weeks in ultrasounds and fundal measurements... yet they don't change the due date . I'm afraid at how heavy he feels (and I've had 3 my largest being 8.10 and never felt a baby this heavy this early) he's coming earlier then what they say
