Well. are you really sure of it that you will never would have want a baby? Tubial ligation is a kind of birth control process that is permanently letting your infertility stuck up. That you can no longer be pregnant after that. What if you change your mind? If you are really sure about it, then go! But remember, there's no point of returning back after you decide.
It surely takes a lot of guts to be able to have tubal ligation. I believe that once you have this kind of birth control, it's already permanent and no more pregnancy to expect. So, if it's what you want..make sure you don't regrets with your decisions in the future because once it's given, there is no turning back.
Tubal ligation is no joke. You need to think a lot harder before you undergo this kind of birth control. Inferitility would be premanent and you would no longer have a chance to have another baby if you have this method. So, just think a hundred times before deciding on this.
