"i stopped taking birth control pills because of the hassle of remembering to take them. my doctor recommended nuvaring due to the convenience of using it and being a busy college student. however, two months after using it i had major abdominal cramps to the point where i couldn&#039;t walk. turns out i had endometriosis and had to have surgery, it was not nuvaring&#039;s fault. i was instructed to switch it out every 3 weeks instead of 4 to skip my periods; however, i have yet skipped a period and it has been 3 months since my surgery. i bleed for 2-3 weeks every time. i am switching birth controls to something more stronger since that is what my doctor recommended. other than that, no other side effects at all."
