Baby Weight

So i've seen a lot of girls bounce back to their pre pregnancy weight ( bodies ) but I noticed they are all skinny girls. i'm just wondering what if you weighed more ? what happens then ? I was 165 when I got pregnant actually a little less than that and i've gained 27 pounds so far but i'm already on my 9 th month. I'm curious will I bounce back to my pre pregnancy body ? Or not ? 
This is my first baby
