Not many symptoms at 10 weeks...normal?

I will be 10 weeks tomorrow and around week 5 and 6 I had lots of morning/early afternoon nausea but never actually vommited. Since then I have felt pretty good with little to no nausea. Every now and then I feel a little nauseous but nothing bad at all like it was before. At my first Dr. appointment last week the ultrasound lady asked how I'd been feeling and I said surprisingly pretty good. She told me I was lucky, and I very well probably am, but I'm just wondering if anyone else is feeling this way...not having too many pregnancy symptoms. I know baby was perfect during the ultrasound, good size and great heartbeat but I can't help but wonder if everything is ok! I guess at least when I was nauseous I knew there was something going on in there ;)
