Need assurance

I just need some assurance. I haven't experienced morning sickness, how ever I do feel nauseated at some point every day. I Don't have much of an appetite right now (the thought of chicken really grosses me out.) I guess I know I'll probably be told to be thankful but I guess I'm a little discouraged that I'm not feeling more of the symptoms of being pregnant. I'll be 12 weeks this Saturday. Just wondering if anybody went through their 12 weeks with little to no symptoms. The only reason why I found out that I was pregnant was because I was having extreme cramping but I was about three weeks along.
