"i just received this birth control a while ago. i didn&#039;t even get my period which was due in a couple days after. the only bad thing is that my back cramps and headaches have gotten worse but it may just be my pms. i am not experiencing any of the other side effects yet. the insertion was only a little painful, but even the weakest of heart could handle it. i would recommended this for anyone who does not want anybody to find out that they are on birth control, and it is a sure thing that you will never miss a pill, or a shot."
