Not having morning sickness?

Hey ladies I am currently 7 weeks pregnant with my first and I'm just wondering if anyone else isn't really getting morning sickness? I've only been nauseous/ gagging a few times & I haven't thrown up yet... My only real symptoms are very occasional cramps and breast tenderness & sometimes I really just don't have an appetite for anything even when I feel hungry (which is not normal for me) my favorite foods just don't seem appealing ... Is this normal?? I still have 2 more weeks until my first ultra sound visit!
