Bump size for baby #2

This is my second baby and I have been getting really self conscious this time around. People keep commenting on how big I am and making jokes about my size. I am definitely bigger than I was with my first.. Photo on the left is me at 24 weeks today compared to me at 26 weeks for my first baby on the right. 
Mummies of 2 or more - does the extra weight gain continue all the way through? Like, at 40 weeks am I going to be bigger than I was last time or does the weight gain slow down after a while? I felt like I was HUGE at 40 weeks last time and am freaking out at the thought of being even bigger this time...
