birth control
"I had the Implanon Implant put in October 2009 and have felt it has been the best choice for me. My period is irregular, I never know when I'm going to get it but so far that is the worst part I have experienced, my weight has stayed steady and have had no pregnancy scares, since my period has become irregular and sometimes spaced out by 5-6 weeks I will sometimes take a pregnancy test to make sure it is indeed working and so far so good, thumbs up from me."
