Mild to moderate swelling in pregnancy is perfectly normal and to be expected. My wedding rings came off at about 32 weeks and this weekend, at 33 weeks, I had to go get new shoes 1/2 size bigger than usual. My sister had swelling so bad in the 3rd tri that she could only wear socks and slippers comfortably.
It is important to note that very SUDDEN and severe swelling (including more of the body than just feet and hands usually) can be a sign of pre-e, so make sure you keep your doctors appointments. If you have sudden swelling or it becomes severe, call your doctor. It also couldn't hurt to take a trip to the drug store and have your BP taken in one of those machines. I actually bought myself a $20 home BP machine to keep tabs on my pressure; I check it every day. But it sounds like the kind you are having is to be expected.
