How is everyone's mobility so far?

I have been cruising along but as soon as I hit close to 37 weeks I suddenly am swelling up all the time and in intense pain? It's actually a little depressing as I still have things I'd like to sort out but it's almost like I really can't... smallest task takes my breath away, swells me and causes me pain that I promptly have to lie down for a while (mostly for swelling). How is everyone else going with their mobility during pregnancy? Please don't tell me it's only me
