Firstly congratulations on your pregnancy!! If you go to bubhub dot com dot au (sorry cant post the link) they have a services directory with lots of places that do pregnancy yoga and all sorts of other pregnancy classes! If you havent done it for a long time you will need to take it very easy - and obviously let them know that you are pregnant! I also bought a pilates and yoga dvd on ebay so i could work at my own pace at home and found that great. Aqua aerobics was really good later on too! Good luck with it all!
