I am about a size 12 and always had a flat tummy. I started showing at 6 weeks mate and now at 14.5 weeks look really pregnant! I couldnt wear alot of my pants from very early coz they were too uncomfortably tight on the waist, DOH!
They did say at the first scan that bub was slightly bigger than normal too... soooo hoping that doesnt translate to 9 pound birth weight youch!

LOVING my big bump though :-)
