Weight gain?

Karla
So I'm overweight when starting 259lbs and my dr wanted me to watch it.  I'm coming up on 30wks and weighing 266-267lbs.  She doesn't want me to go over 270lbs. I also have pcos so it makes it hard to get it off on the other side.  I just feel like I'm so weight conscious now and nervous about going over 270lbs.  How is everyone  else's weight gain going and what are you doing to help keep it down?  Thanks- ftm
