If you have the entire uterus cut out, but leave the ovaries and the cervix you will never have a period again Hallelujah!!! This is what I'm planning on doing in two months time. This also has the added bonus of preventing you from needing hormone pills as your ovaries and cervix are still producing the hormones you need. Usually they will even increase production to meet the bodies needs if there is a drop. Happy days no more periods!! No pregnancy either which is super nice!
Good luck!
