I'm getting towards the end of the first trimester and so far my weight gain is spot on with my first pregnancy.
I gain about 7 lbs immediately, then I get nauseous which stops the feeding frenzy and I end the 1st trimester up 5 lbs from pre-pregnancy. I'm hoping the rest of the weight gain is similar with my last pregnancy but since most people don't even gain their first trimester I've still got a long ways to go.
