What are some things I can do to pamper myself while pregnant?

Whatever you like. Take long walks, listen to music, eat ice-cream, get a massage, get a pedicure, get a manicure, watch a favorite movie on dvd, go out with your girlfriends, go out with your boyfirend/husband, essentially whatever you want as long as it is not harmful to the baby inside you. Enjoy!
Exercise, massage. Regular exercise will make you feel better. Yoga and massage can help you relax and ease your sore muscles. Manicures/pedicures, new haircuts can help you feel more attractive when you're starting to feel like a beached whale.
