Can someone explain how exactly "morning" sickness feels? I have not been vomiting, and have not had any really severe nausea, but I have noticed that my stomach is very easily upset after some meals. It isn't all the time, but when it happens it is strange because I am not someone who vomits or gets nauseous easily or frequently. I have the same lunch every day at school, and the only time I have ever felt weird after eating it until today was when I had the flu last month.

I am not pregnant yet (as far as I know so far...), but I was wondering that since this is out of the ordinary for me, could this be early pregnancy sickness?
