When did you start to show?

I am 10 weeks 1 days pregnant. I know that every woman shows at different stages, but I would like to know when everyone started to show. I have actually lost weight in the last 6 weeks (3 lbs) due to food aversion and nausea. My stomach looks a little bit smaller than before even though my pants are definitely becoming more snug, The pregnancy is progressing like it should acoording to my sonogram yesterday. When should I expect to see a difference in my belly?
