She's a member of a group called Feminists For Life, which is a pro-life organization. I find the logic internally inconsistent, so I can't effectively answer your question, other than to simply point out her membership in that group.

However, as leora points out, the reports about specifically which methods of birth control she is against are contraditory, but as a proponent of abstinence-only, that philosophy includes anti-birth control sentiments, so regardless of the contradictory reports, her self-inclusion in the abstinance-only program implies, to me, that she is actually against all forms of birth control.
