Hi mummies, found this on the net with regards to water retention. Hope it helps.
Ways to fight bloating during pregnancy. Water retention or ‘bloating’ is usually a result of rising hormone levels which cause you to retain more fluid than you would normally.
Luckily there are a number of different ways to help reduce the effects of this during your pregnancy, and some of these include:
1. Lie down or elevate your feet regularly. Try and get your feet elevated as much as you can, especially during the third trimester.
2. Avoid wearing tight-fitting clothes, shoes or stockings as these will only restrict the blood flow and make your fluid retention worse.
3. Exercise will also help you a great deal with fluid retention, try swimming, yoga or walking.
4. Avoid diuretic drugs, especially during the early weeks of pregnancy.
5. Drink water- try and ensure that you are drinking at least 6-8 glasses of water a day. You should be doing this even if you are not suffering from fluid retention anyway.
