Anyone else?

Cassidy • 1 little boy who has me wrapped around his finger, miscarriage, and rainbow baby coming this year. Been married to my hunk since 11/11/2011, life is full of the sweetest surprises.

I am 29 weeks, at my 27 week appt my doc told me i was measuring 2 weeks ahead. At all my previous appointments i have measured exactly on track for my due date. I dont have gestational diabetes, what would cause this rapid growth and should i be concerned?
