Weight gain while pregnant

During my first two pregnancies I gain 60 lbs each. The first one I didnt watch what I ate. But the second time I ate way better. I just found out I'm pregnant again and still had 30 lbs I wanted to lose. And if I gain 60 this time I'll be way over 200 lbs and absolutely dont want that. What advice do you have to not gain any unnecessary weight. I'm terrified of gaining to much again.

Also during my first two my job didnt have me moving around much. I'm currently at a job where I'm on my feet all day so I'm hoping that helps me this time.
