Congratulations on your pregnancy! i pray that everything is going well!!
i know that Medical Center of Plano offers water aerobics in their aquatic center and what a great place to go to!! you could call the hospital to find out more about thier water aerobics classes. we delivered our first baby girl there in 2003. wished we had returned the second time around...
anyways, i don't know if they offer discount for their classes if you deliver there but it's worth asking. make sure you get a doctor's prescription saying it's alright to attend the class. i remember i had to get a script for a prenatal massage--which i never got and need everso badly! LOL
best wishes on your pregnancy!!
