I'm always confused about why you attribute women being the leader of the family's domestic life to "conservative" women. Lesbians, liberal women, single women with children, really most women (of course there are important exceptions) are the people in their families who make the domestic decisions. I call "conservative" people backward because they blindly support an abjectly corrupt party in order to have their backward religious views forced on their fellow citizens. Conservatives in no way have a monopoly on family life, ethics, quality relationships, etc. 
I have no problem with conservative women saying, "Because of my religion, I don't think I should use birth control." I have a problem with them saying, "Because of my religion, you can't use birth control."
