"i got this implant in october 2015 which was about 10 months ago. worst decision of my entire life! while it did its job by not getting me pregnant it has a ton of side effects. first my arm gets the extreme pains where the implant is at random times. when i got the thing i was around 210 and i had recently just lost 50 pounds and i was feeling great about myself. well now i weigh 281 and i believe it is because when i got the implant i started to crave certain foods and they wouldn&#039;t go away until i had it. the third thing is it made me extremely moody all of the time. my family and i have and i have been evaluating my behavior and i get angry for no reason all of the time. last thing my periods happen 2 a month and they last 7-10 days!"
