"i have had the implant for 3 years and am due to get it taken out next week. whilst the implant has been effective at stopping pregnancy, i have had a lot of unpleasant side effects. one being weight gain, i have gained around 2.5 stone and always seem to bloated. period wise, for the first year and a half i had no periods whatsoever until they came back and i got very light but painful periods every few months that lasted 2 days each time. other things i have noticed are i get pain in my breasts occasionally, poor sex drive, bad mood swings and worsened eczema. i don&#039;t plan on getting the implant again due to the side effects, however it seems to be effective at stopping pregnancy and stopping periods or making them light."
