"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&#039;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."
