Swollen foot? 36w2d

I’ve been dealing with swollen feet for over a month now. Blood pressure is normal, blood work is normal but they really swell so much it’s hard to walk on them. Anyone else have this issue? I’m also getting white blotchy spots all over my legs. Doc just said to elevate feet. My left one is always more swollen than my right one. I can’t even do much without it starting to swell 😭
