careful with the jumping if you do aqua tho - aqua is pretty much great for being preg as youre supported, but any jumping is def a no no as your muscles down there are all moving about and dont need to be wrenched when you hit the ground. Ive also found that any jigging about like water running sets my muscles off twinging too, so i cycle my legs or kick with a woddle under my ass so that i still get the aerobic affect. Just be careful and if anything feels weird/hurts, stop. dont force yourself through.
