Can't use birth control nor the depo-provera shot cause i bleed a lot and my bf refuse to wear a condom. is their a way to prevent pregnancy? don't want kids

Yes but: Please alternative methods of birth control including the Ortho Evra patch, low dose estrogen pills, low dose progestin-only pill, intrauterine device or the nuva ring that may better suit your body and/or lifestyle. The withdrawal method or the calendar method will not prevent pregnancy although it may decrease your chances of becoming pregnant.
