No morning sickness . . . normal?

I'm somewhere around 5 or 6 weeks pregnant (won't know for sure until I see the OBGYN for the first appt. in 3 weeks. So far, I have had a slightly elevated temperature, on-and-off tender nipples, and some mild cramping as my symptoms. Today, for the first time, I felt very slightly nauseous, but so slight that I don't know if it was really morning sickness. I simply haven't had that awful nausea/vomiting that most women experience. I know that morning sickness is a sign of a health pregnancy, so I'm rather eager to experience it, as weird as that sounds. Is it just too early? Or am I right in the morning sickness phase and just not having any?
