I did in my first pregnancy, as the weather was warm and I was run off my feet at work. Even at 4 months during the really busy days, especially if it was hot. The next 2 pregnancies I timed so they were over winter, and I'm at home with the kids now, so while I'm run off my feet, I can still pause to put my feet up whenever I need to... But this pregnancy is very similar to the first one so I suspect I'll get swollen feet and ankles at some point...
Yes!! I am almost 23 weeks and the swelling in my feet and ankles started a few days ago! I take a kitchen towel, wet it and put it in the freezer. When it is frozen it is easy and nice to wrap around your ankles and feet while you elevate them :)
