"i got the implanon about 4 years ago and at first i thought it was great. the pill was giving me serious migraines so that&#039;s why i made the switch. for those four years i had the most irregular periods (some lasting months at a time, and then not having one at all for 3 months). i kept thinking it would get better, but it didn&#039;t. weight gain was another noticeable problem. gained 40lbs. i didn&#039;t blame the implanon until i started doing research and noticed that was a top complaint amongst women who used it. mind you, i tried to lose weight by dieting and exercise and i kept gaining. so i made an appt. to get it taken out. back on a low dose pill and feel so much better. no headaches and down 6lbs in a little over a month!"
