I think if you told your doctor you are ready for permanent birth control and you were pressured/redirected to follow the doctors course, then you should find a new doctor. You are your best advocate and you know what is best for your body and your family. Do not let someone else make that decision for you. Planned Parenthood's site has a great BC reference section that could give you a better idea of all your options and you can research more from there. Good luck.
