"i had the implanon about 7 years ago and had it taken out after only a year (not the 3 its allowed).  this was a horrible experience for me. i didn&#039;t have a period he entire time, i gained almost 50 lbs, had the worst mood swings, i could feel myself becoming angry/crazy even though often times it was not that serious. everything made me mad, or made me cry-- just horrible. after having it removed, it took almost 2 and a half years to start my period again and another 2 for it to become regular! when i did first get it, i had a period every 4-5 months. now that it is a bit regular, i still can not seem to get pregnant. worst decision i ever made was getting the implanon. never again, nor do i recommend to anyone"
