Is it normal to show so early?

So, I'm currently 8 weeks pregnant. At first I thought it was because I was very gassy. But from the pictures I've been taking I noticed a tiny bump. I started to do a little research and heard that you're supposed to only start showing at around 11 weeks. Is it normal or is it just gas? The "bump" is very round and low on my abdomen, nothing like when I'm about to get my period. I wish I could post a pic but the sub doesn't allow.
