When did you start showing???

Samantha • Married to the love of my life. Healthy 1st baby (boy) 10/07/14 after a long road to pregnancy. Couldn`t be happier!!!!
For those of you who are farther along in your pregnancy's or have had a baby previously, when did you start showing?? I am only 8 weeks 4 days but curious to know when you noticed a bump. If I try and suck in my stomach I definitely can't suck in as far as I used to but I'm still basically flat. I am 5'1" and 104lbs so don't know if that makes a difference? Thank you!!!
