No morning sickness?!

I'm now 4 weeks 5 days pregnant with my 3rd. With my first two, boys by the way, I got hit with HORRIBLE morning sickness the day I found out with my first (4 weeks for both) and within a week with my second. I have known now for almost 2 weeks and I feel amazing for the most part. A few dizzy spells and tiredness, but if I haven't had anything like the last 2 pregnancies do you think I will get it still?
