Weight gain emotions

I know I am supposed to gain weight, but is about 4-5 lbs in the first trimester ok? I weighed myself and had an emotional reaction to being almost the weight I was in college, post freshman year. I've weighed myself, counted calories, etc for about as long as I can remember and I'm scared that watching my weight go up and up will rob me of the joy and excitement of pregnancy. Please no rude comments, feeling a little fragile.
