Americans don't have universal healthcare, can't just go walk in some clinic / pharmacy and get a doctor / pharmacist to Rx you some birth control.

You also have minimal->zero private money and come from a poor background so it's too expensive. Your parents are religious and it's difficult to privately have & use birth control. Copper IUDs create pretty bad periods and are more painful to insert if you never given birth. Giving yourself a megadose of hormones with other implants is pretty freaky.

But your 16 years old and have a lot of hormones...

That is part of the reason why the entire obamacare free birth control fight was pretty emotional in the USA.

I'm pretty sure that you can buy condoms in America. They're not that expensive and work reasonably well.

Last I checked condoms were the only birth control that prevents STDs. All the other birth control named is not appropriate for teens who are unlikely to have settled on a lifetime monogamous partner.
