Sudden cellulite

I had normal sized legs before pregnancy with little cellulite. Since getting pregnant (now 23 weeks) my legs have gotten huge. I'm talking stretch marks all the way around and all the way to my crotch. Plus an explosion of cellulite that is so bad you can see it thru my pants. I even think my legs don't move apart when I walk from the knees up. Does this go away? It's making me very extremely upset.
