When do you start to see signs of pregnancy?

the moment you know your pregnant,how long until your body starts showing you signs?

I've never been pregnant so I'm not sure but I'd say around maybe 3 months or so.

when I got pregnant, I did NOTHING but sit around and sleep...I thought I was just getting sick...and then one night my fiance and I decided I should PROBABLY check because I was late and I AM pregnant...it took a couple weeks for my to REALLY start showing any sort of signs that I might be...but honestly its WAY less than three months...
