overweight & baby bump?

Denise

This is my second pregnancy.13w 3d today, I'm starting out heavier than with my first. I'm 5'9 & about 215 pounds, I do carry extra fat/skin mostly on the lower part of my stomach. I'm not really showing yet...I can tell the top part of my stomach is more rounded & sticks out but not the lower. A bit odd. Just wondering when did you ladies who where/are on the heavier side start showing or when could you really tell yourself? :)
