I'm pregnant with my 3rd and luckily haven't had any morning sickness. (yet) I didn't have any with my 1st either, but my second, I was sick for the entire first 3 months (morning, noon, and night). Had to stick with plain bagels, oatmeal and crackers, but had to really make myself eat, even though sometimes I knew it would be coming back up. Even some strong smells would make me sick. My doctor wasn't too concerned. It can be very common during the first trimester. If you become concerned, just talk to your doctor about it and I'm sure they'll put your mind at ease. Hope this helps.
