Hi girls
It is a pregnancy thing. Often caused by rosing your feet/legs or sitting at a slight angle and putting a little more weigh on one buttock/leg than the other. Sleeping on your side can also cause this. If you have no other symptoms then it is not a problem. To help to reduce the swelling try not to sit for too long without going for a short walk. If you do need to sit for long periods then doing some foot/leg exercises may help. Don not cut back on your fluid intake thinking this will help. It wont, but it will cause other problems.
