Hi HotMumma

Aquaerobics are fine. They are probably one of the best forms of exercise during pregnancy. You do not need to go to a pregnancy specific class you can go to any, just make sure that they know you are pregnant. Your level of exercise would depend on your pre-pregnancy exercise and fitness. You can exercise to the same level as you did prior to becoming pregnant. If your pre-pregnancy exercise level was low or non-existent then start of with something light (eg just walking in the water) and slowly build up.
Thanks Alan,

I want to do aqua as I have been reading it is the best forms of excercise while being pregnant. I will have to start with something light as my main form of excercise has been nothing other than walking the shops as it has been so hot.
