Brief Summary:
The purpose of this study is to evaluate if changes to the FemBloc Permanent Contraceptive System are effective in increasing reliance (the ability of a woman to be able to depend on FemBloc for contraception once the treatment and confirmation test have been performed), and decreasing pregnancy rate. In addition, the study will compare the FemChec confirmation procedure to that of fluoroscopic HSG, a well-established method of confirmation.
