Morning Sickness

I'm sure this is a silly-ish question that I could have found in the archives, but none the less...

I am not experiencing "morning sickness" the way I did with my first (pre-op) pregnancy. I feel nauseated almost constantly, but haven't vomited. I suspect that it's because I physically CAN'T unless I've just finished eating. Am I totally off the mark? What were/are your experiences with morning sickness?

 I have no answer for you, but I am 10 weeks pregnant and have been nauseous all day for the pas two weeks....the biggest thing that scares me is that I have lost 6 lbs (and I haven't lost weight in months) and that I really cant eat meat or even think about meat, or protein shakes, it all makes me sick...its bad news
