11 weeks, not showing AT ALL


I'm 5 foot tall (153cm) , 45kg (99 lbs) and am 11 weeks with my first baby today. I had a bit of bloat a few weeks back but at the moment my tummy is completely flat. Like completely. Flat. 😐 First scan is next week when I will be 12 weeks. I'm so worried something is wrong. I keep seeing lots of other ladies on here with their little bumps already and can't help but feel abnormal. Anyone else experiencing the same thing? Is it because I'm petite build?
