I know how you feel about periods and pregnancy -- pregnancy squicks me out as well, and before I got an IUD my periods were actually monthly assassin attempts by my uterus. I would also have no problems with removing my uterus, considering all it's brought me is suffering and stupidity.

I wish you best of luck with the surgery! If my uterus keeps up its "get more evil as I get older", I may find myself pursuing the same thing down the line. For now, the IUD keeps it manageable, though still probably more heavy than most women deal with.
