Is this normal??

I'm 12w3d and I have not been sick AT ALL. Just sleepy, moody & tender breasts. Though I am grateful, it somewhat worries me because I see everyone posting about nausea. I'm also a little crampy now that I'm 12 weeks- nothing painful and no bleeding but it's still worrisome. Thoughts??
