bubbles and soaps should be ok. You might want to stay out of a bath full of fragrances and such while IN LABOR. But other than that relax and enjoy yourself.
As long as the water isnt hot enought to change your body temperature, like a jaguzzi, then you and the baby is fine.
Baths and water are very beneficial to you and your baby. It helps relax and releives pressure off your bones and joints. Try swimming when your feeling bad.
Whenever I have back pain or hip pain I just hope in the pool and swim around a bit. Its good excersise and helps releive the aches and pains. And its summer time soon !!!
