I went to a PP for an exam, and they push birth control pills asking me ever five minutes if I want BC. They also give out FREE condoms and you can get pills FREE and norplant FREE and FREE IUDs. It's free because you fill out a little voucher and the government pays. When I told the lady I pay for my own healthcare and am not interested in BC she looked at me cross eyed *LOL* So yes all these things that GS suggested, are available to anyone who wants it.
The trouble with relying on PP to provide contraceptives is that 1) the girls/women who are responsible and sane enough to go there before getting pregnant, aren't the ones who are having baby after baby and dumping them on the streets, and 2) with adolescents/teens, PP has a hard core ideology that they have to be allowed "make their own decisions" -- which often translates into relying on the pill or condoms, which they then proceed not to use regularly. Out-of-control, unsupervised adolescents have NO business making their own decisions about anything that really matters.
I remember years ago a friend of mine was working as a counselor at an abortion clinic (an independent one, not PP, but they all have pretty much the same philosophy). A black inner-city mother brought her pregnant 11-year-old daughter in for an abortion. The girl was telling her (skeptical) mom that she'd been raped, but was telling the counselor otherwise. And she was also telling the counselor she wasn't sure she wanted the abortion. The counselor -- a white college student from a well-to-do family -- explained to the mother that they couldn't do the abortion until the girl consented, "because she has to make her own decision". The mother went ballistic, yelling "What the h*ll do you mean? She's 11 years old! Chain her down if you have to!".
IMO, this mother had a lot more common sense than the abortion clinic's management. The girl didn't get the abortion at the clinic, but probably ended up getting it somewhere else -- quite possibly a "back alley" type establishment. And if this poor mother subsequently tried to get an IUD or Norplant for her wayward daughter, she'd surely run into the same obstacle at this clinic or a PP clinic. The kid was probably pregnant again before her 13th birthday.
