I agree with Bek, but I don't know how common ankle swelling actually is. I didn't get it with my last pg, and I (to be honest ) don't pay much attention to how common or uncommon it is.

Apparently drinking lots of water helps to reduce the swelling (drinking more = less fluid retention , I don't understand it, but hey, I'll drink to that!) amount. I think I'm about as far along as you, maybe a week less or so.
