Not showing at 11 weeks

Anyone else not showing at 11-12 weeks? I'm 11 weeks 3 days and not showing at all. I don't think I look any different than my normal self. I don't go until Monday to hear the heartbeat so I'm a nervous wreck! I see a lot of women posting baby bump pics at 10, 11 and 12 weeks and I've got nothing going on. Is this normal or should I be worried?
