Swelling

Question for you ladies, I'm 29 weeks 4 days and gradually over the last week I've started to swell like crazy. My hands and ankles the worst. My hands sometimes to the point where my finger tips go numb. I get up and move around every couple hours and trying to drink more water. I plan on calling my dr Monday to see what he says but wanted your opinions. Not a first time mom but feel like it as my first is eight years old.
