Hi! Im 15, and me and my boyfriend have recently started having sex, with condoms, and I still don't let him cum in me even with a condom on. I Really want to get on birth control just as an extra precaution. I told my mom that I wanted to get on it, and she said she would schedule an appointment with her obgyn for me. But the other thing is I have a lot of medical conditions, one being a brain tumor, which is non cancerous, and my mom doesn't want me to take the pill, since it messes with your hormones, and it might make some of my conditions worse. I also have to have MRI'S every couple of months, so I can't have any metal in me, like an IUD . I was just wondering if there was form of birth control that won't mess with my hormones a bunch , and that doesn't have any metal or anything. Thanks
