Hi Ngala.
I had the same problem. my feet and hands were starting to swell up at about 20 weeks. Everyone was saying stuff like 'you shouldn't be swelling this early there is a problem'. I saw my Ob, and to quote him 'you are pregnant, these things are going to happen and yes, don;t worry it is completly normal'. He went on to say that if i had high blood pressure then he would be concerned.
I stopped wearing rings and a watch at around 21 weeks, and am now 24 weeks. My feet still swell up, but rest them when I can.
I would still mention it to your HCP however.
Also the best way to reduce fluid retention is to drink more water as it flushes away the excess toxins and salts that your body. I drink at least 2 litres of water a day, plus diluted juices and milk.
Hope this helps
