Your legs, feet and hands may swell easily because you carry more fluid when you are expecting. Any extra fluid collects at the extremities of your arms and legs. The bigger your belly gets, the harder it can be to put on your shoes or wear rings. The symptoms are often worse after a long day at work or in the summer when the weather is warm. The swelling goes down if you wear compression stockings or rest with your legs raised. If you wear compression stockings, put them on early in the morning before the fluid has accumulated in your legs.
