"i used implanon right after first child only for about a year was very fat got it removed lost the weight but no other side effects. after second child got it again only this time i have terrible migraine headaches, mood swings and weight gain, i have tried losing weight and  eating healthy and i do lose the weight but it has to be a strict diet and exercise routine or else my weight will just come right back i also get my period about 2-3 time a month! for me this is definitely not worth it. getting it removed asap"
