Gaining weight in first trimester?

Is anyone gaining weight yet? I was told we should gain between 1-5 pounds in trimester one, and I am at 9 weeks and about 7 pounds heavier than usual :-/.  Is that a good indicator that I'm going to get huge?! I haven't been exercising as much as I normally do (thanks to constant nausea), and I'm eating more.....I guess I should be more conscious of how much I eat each meal!
